“I really like Bitcoin. I own Bitcoins. It’s a store

of value, a distributed ledger. It’s a great place

to put assets, especially in places like

Argentina with 40 percent inflation, where $1

today is worth 60 cents in a year, and a

government’s currency does not hold value. It’s

also a good investment vehicle if you have an

appetite for risk. But it won’t be a currency until

volatility slows down.”David Marcus, CEO of Paypal
