Newbies, don't mess around with cryptocurrencies! Remember these tips to avoid pitfalls:

Don't go all in! Keep some cash for buying more, going all in is a gambler's behavior.

If you don't understand a coin, start with a small amount to test the waters, don't use real money as tuition.

If there's good news and the price opens high, sell quickly; reduce your holdings in advance before holidays to prevent a crash.

For medium to long-term investments, buy and sell in batches; for short-term, follow popular coins, and avoid obscure coins.

If you need to cut losses, do it decisively; learning a couple of technical indicators is enough, don't be greedy.

The key is two words: 'Restraint': Control your hands to protect your capital, so you can wait for the right opportunity.
