Forget about boring stocks. Bitcoin is where it's at these days for investors. The virtual currency is now trading at a record high above $8,200. If this keeps up, bitcoin could be trading at $10,000 before the end of the year. The price of one bitcoin has surged more than 735% this year alone and has skyrocketed nearly 40,000% in the past five years. Some investors are likely flocking to bitcoin as a speculative bet. But there's also a legitimate case to be made that bitcoin, ethereum, litecoin and other cryptocurrencies are the future of money and that more and more people will conduct actual transactions using these currencies. To that end, Square - the popular mobile payment service run by Twitter CEO Jack Dorsey - recently announced a trial that will let some users of its Cash app purchase bitcoin. We're always listening to our customers and we've found that they are interested in using the Cash app to buy bitcoin," said a spokesperson for Square. "We believe cryptocurrency can greatly impact the ability of individuals to participate in the global financial system," the Square spokesperson added. And CME Group, owner of the Chicago Mercantile Exchange, said earlier this month it plans to soon list bitcoin futures contracts. Futures let investors buy and sell an asset at a specified price at a later date, They're popular bets for currencies, metals and agricultural commodities. In other words, CME Group is now treating bitcoin as a legitimate financial asset.
