So, youve bought Bitcoin (or another cryptocurrency) and hey! its shot up in value. Good for you. But what do you do with your digital money now? If youve made a serious profit, you might be wary of leaving it on an exchange such as Coinbase or stashing it in an online wallet (after all, North Korean hackers have reportedly stolen almost $90,000 of Bitcoin in the last two years). The most secure alternative is to take your currency offline altogether with a hardware wallet. This is a purpose-built, secure device for cold-storing the private keys that allow you to spend your digital currency. Two of the most popular are the Ledger Nano S and the Trezor, both of which employ open-source code (meaning that even if the companies were to fold, the devices would not be rendered obsolete). We tested them both

The Ledger Nano S looks like a USB stick, except it comes with a tiny screen that means you can operate it independently of your computer (as otherwise it would be vulnerable to malware). The controls are pared back to two buttons on the top of the device, which are used for everything from scrolling through menus to entering your PIN.

Set-up is simple. On-screen instructions take you through configuring your PIN and randomly generating your passphrase. The passphrase is important. If you were to lose or break the device, you can restore your entire balance on a new Ledger by entering this 24-word phrase.

Next, you download a set of Chrome extensions: a main device manager, and wallets for the different currencies you hold. Ledger currently supports Bitcoin, Ethereum / Ethereum Classic, Ripple, Litecoin, Dogecoin, Zcash, Dash and Stratis. If you wish to send or receive currency you do so via these browser-based apps, and your Ledger will ask you to press buttons to confirm that you do indeed want to carry out that function. Without the Ledger plugged in, moving your currency is impossible.

Pros: This is a compact device that has found clever systems to make a two-button control system viable. It supports a multitude of currencies, and is the most affordable of the two hardware wallets on test.

Cons: The build quality on our model could have been better. The left-hand button often registered one click as two, and it encountered problems a number of times during setup, though we succeeded eventually.

The Czech-built Trezor which translates as vault in its native language has many similarities with the Ledger. It, too, has a screen that means you can use it to keep your money safe even on an infected computer, and operating it also comes down to two buttons. The set-up is similar as well its all about choosing a PIN and a 24-word passphrase that allows you to restore the device. How you interface with this dongle from your computer, however, is rather different.

Whereas the Ledger asks you to tap away on its buttons in order to input your PIN, the Trezor displays the numbers 1 - 9 in a random formation, and asks you to click the corresponding buttons on a digit-less pad displayed on your computer screen.

The Chrome app through which you control your Trezor and your wallets is slicker than the Ledgers. It involves opening fewer windows, and the visuals are rather more glossy though it essentially offers the same functionality. It feels like a more expensive product, and it is. The only downside is that, for now, it lacks support for currencies such as Ripple.

Pros: Higher production values, both in terms of software and hardware.

Cons: Fewer currencies supported.

So, you've bought Bitcoin. Now what? - GQ.com

Back in early 2014, thanks to a confluence of digital malfeasance and wide-eyed optimism, bitcoin enjoyed a nice run in the headlines. Things have since quieted in the popular press, but venture capitalists, entrepreneurs, and speculators have continued to work toward the promise of a secure, fast, and cheap payment system that cuts out fee-hungry banks and credit card companies. Following Bitcoins lead, theyve built dozens of competing cryptocurrency systems, and while digital coins arent part of most peoples everyday lives today, its increasingly clear that they will be, sooner or later.

Bitcoin itself, however, wont necessarily be part of the future it has ushered in. A broad surge in cryptocurrency values pushed the original recipe north of $40 billion in late May, but a long-standing issue that limits the systems capacity has left it struggling to give users what it says on the tin: a cheap, quick way to move money. Because bitcoin is open-source and democratically managed, a huge number of stakeholders are wrangling over how to solve this scaling crisis, which hinges on an obscure technical parameter.

In response, the bitcoin community has split into two factions that tout mutually incompatible solutions while accusing each other of incompetence, conspiracy, self-aggrandizement, and generally being the devil. On March 17, more than two-dozen bitcoin marketplaces issued a joint letter warning that there is a very real possibility that a Bitcoin network split may occur in the future if the conflict isnt resolved. It was one of the first high-level acknowledgments that, just as it begins to fulfill its promise, Bitcoin could be torn in half.

The idea of a Bitcoin split, or the extremely personal infighting that has made it a possibility, would have seemed laughable just a few years ago. Then, a tight-knit crew of bitcoin pioneers gleefully nerded out over an arcane innovation with world-changing potential. At the heart of bitcoins radical promise is the so-called blockchain, essentially a ledger where transactions are recorded. But instead of some spreadsheet living on a single computer, the blockchain exists on thousands of servers worldwide that constantly monitor one anothers copies of the ledger. This makes the network essentially unhackablean astonishing achievement of computer science and economic engineering.

Since a still-anonymous creator introduced bitcoin in 2009, its central innovation has given birth to a diverse and thriving ecosystem. There are now dozens of other cryptocurrency systems, with names like Ethereum, Dash, and Ripple, many with more features than Bitcoin. Perceived instability in Bitcoin could eventually push investors and developers to these alternatives. But more profoundly, Bitcoins inability to solve its own problems would cast doubt on its core libertarian-democratic premise: that people dont need the government or banks to manage their currency.

If Bitcoin were to split, it will be because it was just too successful for its own good. Public interest and transaction volume has grown more or less steadily for the past five years, and the blocks that make up the blockchainbundles of about 2,000 transactions compiled every few minutesare getting very crowded. Some transfers can currently wait hours, even days, to go through.

Users can pay a fee to have their money moved first, through a bidding process that is becoming increasingly fierce. Before 2014, bitcoin transactions were effectively free. By October, users had to pay operators about 13 cents to get speedy resolution. Today, that average fee is closer to 50 cents. That removes some of bitcoins appeal as an alternative to, say, Visa, which charges merchants about 10 cents for small transactions or about $1 for the average swipe.

Almost everyone admits this is a problem, but bitcoiners are divided into two camps over how to solve it. One faction is led by Roger Ver, a very early funder of Bitcoin startups who has relentlessly proselytized for the technology since 2011. Among the cultish ranks of bitcoin boosters, Vers commitment and vision earned him the nickname Bitcoin Jesus. Now, he has taken up the banner of Bitcoin Unlimited, a solution to the scaling issue that would directly increase the codes limit on how much data a block can hold.

While this would make bitcoin faster and cheaper for users, critics say it would also make it more expensive to run a server. For this heresy, Vers enemies have rechristened him the Bitcoin Antichrist. One of his main allies, the Chinese server manufacturer Jihan Wu, has been similarly dubbed Jihad Wu, complete with a satirical Twitter account that paints him as an ISIS-style terrorist.

The main competing proposal is offered by Bitcoins central development team, Bitcoin Core, and is known as Segregated Witness, or SegWit. It would free up a smaller amount of space for transactions, while making it easier for secondary systems to handle smaller transactions outside of the main, super-secure blockchain. But it could leave bitcoin proper nearly useless for small transactions.

This may sound like a technical squabble among quislings. But the two solutions imply two fundamentally different visions of what bitcoina system that currently has a higher market value than Credit Suisseshould be. Those who support Vers vision of larger blocks want bitcoin to be a day-to-day, open payments network, usable to buy anything from a cup of coffee to a car. Those who support SegWit are more likely to see bitcoin as digital gold, a long-term store of value that wouldnt move around that much. That would leave fees high but make paying them less necessary, while relying more on secondary systems.

The two factions congregate on separate, opposing Reddit forums where they each tout their solution while meme-trolling the enemy. Each accuses the other of sockpuppetingusing fake social media accounts to create the impression of popular support. (And each side, of course, denies in engaging in such behavior.)

If Bitcoin were a company, youd expect the CEO to sort out his or her underlings petty backbiting. But Bitcoin has no leaders. Instead, the miners that run Bitcoins servers essentially vote on any proposed changes. For years, the consensus version of the software was distributed by the slowly rotating Bitcoin Core team and adopted with little controversy. Core had no official authority, but its expertise was broadly trusted.

But many miners have lost faith in Core, accusing it of moving too slowly to tackle the scaling issue. According to tracking site Blockchain.Info, a little more than 40 percent of miners are currently signaling their support for Bitcoin Unlimited, compared with only 30 percent signaling for SegWit. If more than 50 percent of miners were to support Bitcoin Unlimited, they could force a shift in the entire network. Ver, though, says he would like to see much more decisive margins of support before any changes are implemented, and SegWit requires support from 95 percent of miners before it can be activated.

With each faction so firmly entrenched, theres no sign things will sharply swing either way any time soon. But a smaller group of miners could branch off to form a separate network and an entirely new currency. This split, known as a hard fork, is what the exchanges that issued the March letter were planning for.

Not everyone thinks a hard fork would be a bad thing. Anthony Di Iorio was one of the founders of Ethereum, the most prominent system to innovate on bitcoins core ideas. Should there be a hard fork, he predicts, youre going to have better growth. [Users] will be able to decide. Competition is good. Ver, unsurprisingly, describes a fork as not a big problem at all.

But othersnaturallydisagree. Reggie Middleton is a financial analyst focused on cryptocurrency and runs the decentralized trading platform Veritaseum. A Bitcoin Unlimited fork would be destructive to the economic value of the [Bitcoin] network as a whole, he says, in part because the strength of any payments system hinges on its size.

Middleton is also concerned about Bitcoin Unlimiteds implications for bitcoins governance. Like Ver and most longtime bitcoin supporters, hes a staunch critic of government and corporate power, attracted to bitcoin because it promises to free currency from control by old regimes. But Bitcoin Unlimiteds larger blocks would require more computing power, storage, and network bandwidth to process, which could concentrate mining in fewer hands, making the system both less secure and less democratic.

Once you centralize it, says Middleton, you open it to threats. It would become like the banking system, which is basically greedy middlemen who stand between you and your money. For bitcoin die-hards, there is no greater slur than comparing something to a bank.

For bitcoin die-hards, there is no greater slur than comparing something to a bank.

Ver thinks this position is ridiculous. Bitcoin was once a true grassroots project, with ramshackle servers toddling along in peoples basements and dorm rooms. But the system has already become vastly more power-hungry: Ver points out that a single usable mining server, and its voting power, today costs $1,000 or more. In other words, bitcoin is still a radical political project, but its also big business, and its time to come to terms with that.

Jeff Garzik has a unique perspective on the public bloodletting. Before spending four years as part of the Bitcoin Core team, Garzik was a leader at Red Hat, which helped make the open-source Linux system digestible for corporate users. Someone had to play that insulating role, because it was common for Linuxs democratic community of developers to engage in ideological warfare over lines of code.

But Garzik says that even Linuxs biggest battles cant compare to the hate swirling around bitcoins block-size debate. While Linux fights might have broken out over engineering approaches, and early bitcoin debates revolved around ideology and theory, Garzik thinks something much less abstract is driving bitcoins current unrest: money.

At this point, more than $1.5 billion in venture capital has gone to support blockchain startups, and many have business models that would be affected by how the block-size problem is solved. Blockstream, which employs some Bitcoin Core developers, builds sidechains, the sort of secondary system that would be more in demand if bitcoin itself doesnt start accepting more transactions. On the other hand, theres BitPay, which has sold merchants the idea of bitcoin as a low-fee retail payment system, and for whom the strangled state of the bitcoin blockchain has been a serious headache.

Youre asking developers, in effect, to pick winners and losers in the market, says Garzik.Theres no right answer.

But there could be a wrong answer. A miscalculated change could disrupt bitcoins basic economics, a fine balance of computing costs, coin value, and network demand. And all of those competing blockchains are waiting for a mistake. If bitcoin were to recede, that will be sad for me, says Ver. If theres another iPhone thats better, thats sad for my old iPhone. But it means we get to use a better one. Ver has outlined this endgame scenario on the same portal that he established years ago as a friendly invitation to new bitcoin users. Bitcoin Jesus is now preaching about the looming bitcoin apocalypse.

The viciousness and intractability of the scaling fight could suggest a flaw at the heart of bitcoins core democratic ideals. Maybe, in the end, we really do need authority figures to make big decisionsespecially when theres money on the line. But Charlie Shrem, another early bitcoin entrepreneur who now supports the SegWit solution, focuses on the fact that the software has stood firm amid the chaos. Changes that can hurt the network cant happen easily. Its the same thing with changes that can make the network better. Its what makes the network strong. Its beautiful. His opponent, Ver, sees the same silver lining.

Its not surprising that the two would share a sanguine perspective on the chaos gripping their lifes work. Though nominally antagonists today, Shrem and Ver have a friendship rooted in years in the bitcoin trenchesVers first investment was in Shrems bitcoin payment startup. Shrem says Ver (along with a lot of other people who hate each other on the internet) will attend his upcoming wedding.

In the aftermath of the exchanges March letter, the tension over scaling has continued to ratchet up slowly. New proposals have attempted to break the standoff between Bitcoin Unlimited and SegWit, including one that some say subverts bitcoins basic decision-making process. A version of the SegWit solution was successfully activated on the bitcoin alternative Litecoin, demonstrating that its ready for the big leagues. But still, the deadlock holds, bitcoin is left with the slow and expensive status quo, and neither side is truly happy.

And maybe thats just what democracy looks like.
