To buy BTC, you just need to shuttle it into the position you think is suitable and leave it there. To buy mainstream currencies such as ETH, SOL, BNB, you need to spend some time looking at various data and research reports to judge trends and fundamentals, and recharge your faith. To buy high-quality altcoins such as AAVE, UNI, LINK, etc., you need to invest more time in reviewing on chain data, keeping track of project dynamics, and constantly monitoring the comments on the founder's Twitter and forum analysis. Buying junk knockoffs, all you can do is spend a pitiful and messy life watching the K-line every day, wanting to cry but unable to shed tears while cursing the stupid banker project team.
