The market is recovering, and to select altcoins, one must choose the leader of altcoins, Eth. Only when Bitcoin drops, and the second coin does not follow the drop, can the vast majority of altcoins truly welcome the altcoin season. I choose to dollar-cost average into ETH and BTC on Binance; ETH stands at the application layer, while BTC stands at the value layer, each having its own merits. Previously, when ETH was at 3000, I chose to hold firmly, and now at 3500, I must work even harder.
