1: Do not trade with debt; trading with borrowed money is overextending yourself. This is the most important.
2: Those who trade contracts will ultimately lose everything.
Newcomers should never touch high-leverage contracts. Because human desires are infinite, when you make a profit, you want to earn more; when you incur a loss, you want to break even. After trading a hundred times, even if you lose control once, all previous profits plus the principal will disappear.
3: Connect with some veterans in the crypto space.
4: You can spend a little money to join some paid groups. Who to choose is up to you, provided you think this blogger is reliable and can really help you learn something, such as their trading strategies.
5: Do not buy hot coins.
When a coin is at its peak popularity, or when the market is frantically trading a certain coin, it is basically approaching the end. At this point, if you have held this coin beforehand, you might consider selling. If you do not hold this coin, it is best not to enter the market, as there is a 90% chance you are just buying at the top.
6: Do not play on small exchanges; small exchanges always carry the risk of running away or disconnecting, at which point all your funds may become inaccessible.
