$BTC The upward trend of Bitcoin is above 89,000. If it breaks below 89,000 and cannot go up, then almost all altcoins in the currency circle will be cut in half, so 89,000 is very critical. There is still some hope for 89,000 to hit the previous high of 94,000 or even 100,000. If it can't hold up, be prepared for all coins to be cut in half and just buy the top.
