Strongly recommend that beginners only trade one or two coins. Coins like the big BTC and big ETH usually rise and fall together most of the time, and in the US stock market, storage stocks such as SanDisk and Hynix behave the same way. With the same margin, the profit/loss ratio is identical, so we only trade the most standard ones: big BTC and SanDisk. If you’re more aggressive, best to watch the charts closely; don’t ignore the screen—use stop-losses even when you’re not watching.
