San Francisco’s Crypto Castle is booming in bitcoin rise

In this San Francisco ‘castle’, over half a dozen residents have become millionaires investing in cryptocurrencies such as bitcoin.

Dubbed the Crypto Castle, the three-story house in San Francisco’s Protrero Hill neighborhood houses a revolving cast of young entrepreneurs united by their passion for bitcoin.

As the price of bitcoin has shot up nearly 600 percent of the last 12 months, to more than $4,000, many of them have minted big bucks.

Cryptocurrencies, of which bitcoin is one type, have shot to prominence in recent years as a radical new way to verify actions and transactions. 

They rely on a public ledger, called a blockchain, that is virtually impossible to hack or forge and has implications far beyond making online payments.

Jeremy Gardner, 25, first rented the Crypto Castle in 2015 as a base for his startup Augur, which uses blockchain to run a predictions market.

The house became a landing pad for other young bitcoin entrepreneurs, who mostly sleep in bunk beds.

One, the founder of a self-driving car company that now has over $3million in funding started out living in a basement closet in the house.

‘Over a half-dozen people in the time they’ve lived in my house have become millionaires as a result of crypto,’ Gardner told Business Insider.

Meanwhile, the fate of crytocurrencies is far from certain.

Some believe that bitcoin is in a bubble, similar to the dotcom boom of the late 90s.

For the freshly minted millionaires of the Crypto Castle, the choice now is whether to cash out while they’re ahead – or double down.
