A letter from the US government informed him that: You have not demonstrated that you have the ties that will compel you to return to your home country after your travel to the United States.

Ver officially lives in Tokyo, where he moved in 2005 after serving a ten month prison sentence in the US for selling large firecrackers on eBay, which the Department of Justice described as dealing in explosives without a license. However, he has a second home on Saint Kitts, a small island in the West Indies, which is where he was applying for the visa from.

Bloomberg reported in June that Ver had started a service offering a passport from the Federation of St. Kitts and Nevis - which allows international travel to many countries without the need for visas, and a low level of taxation - in return for a Bitcoin payment. The small government had offered a similar service since 1984 but residents of some countries had found it difficult to get the necessary $400,000 real estate investment out of their own countries. Ver hoped that the unregulated nature of Bitcoin would make that process easier.

Speaking to Coindesk, Ver said: I would be fine with them denying my visa if it was for a valid reason, but they are either lying, ignorant, or stupid when they claim that I plan to secretly overstay my visa and live as an illegal immigrant in the USA."

Ver bought his first Bitcoins in 2011 at a price of around $1. Since then they have risen dramatically to as high as $1,242, but have since fallen back to around $287.

Since then he has been extremely active in the Bitcoin startup community, funding several companies and often handing out coins for free in order to raise awareness of the currency, earning him the nickname Bitcoin Jesus.
