The recent altcoin pullback is linked to Ethereum. The sensitivity of altcoins in this bull market is very high; as long as Bitcoin and Ethereum show signs of sideways movement or pullback, altcoins are the first to drop, unlike before when they would only react after BTC and ETH pulled back. This also indirectly reflects the principle of altcoin promoters, 'only sell coins and do not pump prices.' However, if the market continues to trade altcoins like this, it would be better to just hold Bitcoin. Coins that only think about making a quick profit and then leaving should definitely be avoided.
