“I know these things are super volatile, like some days they can go down 80%,” Humphrey Yang, the personal finance expert behind Humphrey Talks, previously told NextAdvisor. “But if you believe in the long-term potential of [Bitcoin], just don’t check on it. That’s the best thing you can do.”
Virtual currencies. Like fiat currency, virtual currencies such as Bitcoin, Litecoin, and Ether are intended as a medium of exchange that enables two parties to transact business. But there are important differences: No physical coins or bills. Virtual currencies exist only in computer code. Except for visual representation of Bitcoin and altcoins in advertising and displays, and coin-like tokens that may be produced for marketing purposes, there are no actual coins or bills. Not legal tender. Virtual currencies are not legal tender and are not issued or backed by a government. However, many virtual currencies, which are called convertible virtual currencies, can be redeemed for fiat currency on a number of exchanges. No regulation. Virtual currencies are not regulated by any government agency or authority. However, regulation is being considered, especially where virtual currencies function as securities when they’re used to raise capital and when traded on exchanges.
