Waiting is necessary, otherwise the cryptocurrency market is not good now. You are very risky to buy coins blindly unless you are a long-term investor, so you buy Bitcoin directly because it is very cheap now. But don't buy altcoin, the altcoin may disappear.
Altcoin that doesn't have potential will disappear, so choosing and doing research is a wise step. In crypto, the attitude that is able to benefit is to wait patiently. Crypto has two negative and positive functions, all of which depend on the user.
