What are the DOs and DONTs of bitcoin trading?
Simply, never buy at high and never sell at low. Just follow the law of supply and demand and apply everything you've learned in trading such as technical analysis, fundamental analysis, and etc.
Also any other advice for a beginner would be helpful.
Just a piece of advice, never depend on someone's analysis. You may use their analysis as reference but the final decision should still based on your understanding.
Also, what are the best sites to use for trading through experience? Complexity doesn't matter to me. Thanks in advance for any help I receive.
I recommend Binance for wether begginers or veteran traders. It's not complicated to use and it's user friendly at the same time
