As an inexperienced and gambling person in trading, who has lost more than 12,000 $ in crypto and is now only recouping losses, I advise:
1. Concentrate on one maximum of three coins in which you will trade.
2. Set yourself limits on the number of transactions per period. Overtrading is a huge problem for beginners.
3. Do not trust messages in the feed about buying or selling any coin. Study the metrics and focus on your knowledge.
