Altcoins want to have a sustained outbreak, mainly depending on Ethereum. The first step is to stabilize at 3000, the second step is to break through 4100. Currently, Ethereum is still being constrained by Bitcoin, and the exchange rate is still at a relatively low point. According to last week's data on institutional inflows and outflows, many institutions and enterprises are also adapting to Ethereum. Support is at 2800~2900. For Ethereum to have an independent market trend, altcoins can have sustainability; otherwise, it will just be a rapid rise and fall.
