(BTC) trades 24 hours a day, seven days a week. It is a market that never sleeps, and the BTC price is constantly changing. It doesn’t matter which currency or commodity is used to measure how much a bitcoin is worth — BTC is always live and the market is always open.
It wasn’t always that way — in the beginning, before around 2010, there were no exchanges or even reliable price information, and traded at tiny prices — at one point even less than a single U.S. dollar cent. Since those days, however, the Bitcoin price has gone up millions of percent.
