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."
