I found a problem. This wave of Bitcoin rose to the previous high of 73660, trapping billions of short positions from those who shorted at 69000 and 70000. However, ETH has been merciful, giving both longs and shorts the chance to make money and recover, because after Ethereum rises, it just waterfall back to the original position.
Bitcoin is really too strong. When it was sideways at 72200, Ethereum and altcoins continued to waterfall back. This Ethereum is really weak. The first support for Ethereum is around 2610, and the extreme support should be around 2570.
Bitcoin's supports are 72000, 71300, 69800. $BTC
