Probably a big change in the cryptocurrency market. The change may be downward. Because the price of Bitcoin is going down a lot. Bitcoin prices have been falling for the past few days. If the price of Bitcoin goes down, the price of all coins will continue to go down. A few days ago, the condition of other coins including Bitcoin was much better. But as the price of Bitcoin, the main currency in the cryptocurrency market, has fallen, so has the price of other coins.
