When trading cryptocurrencies, there are three things you must remember not to do:

1. Never follow the trend and buy in when the price is rising; you must learn to think contrarily. Be brave when others are scared, and be cautious when others are excited. Get in the habit of looking for opportunities to buy when the price is falling.

2. Never put all your funds on a single trade; it's too risky.

3. Never operate with a full position; being fully invested will leave you immobile. There are plenty of market opportunities, and being fully invested means giving up other potentially good opportunities, which is too costly.
