The market is warming up for altcoins, so we must choose the leader of altcoins, Eth. Only when Bitcoin drops and the second-tier coins do not follow the drop, can a large number of altcoins truly welcome the altcoin season. I choose to invest in ETH and BTC through dollar-cost averaging on Binance. ETH stands at the application layer, while BTC stands at the value layer, each having its own merits. Previously, I chose to hold firm on ETH at 3000; now at 3500, I must work even harder.
