I believe that so many traders have made certain mistakes that they wished they could go back in time to correct. Well mine was actually following advice from friends who posed as experts without doing my own research.

A friend would say "Buy this coin now coz it is going to pump in days or months to come" and without even thinking I would just rush to buy the coin- no research, no planning, no strategy, nothing at all.

Sometimes I made profits from this coin no doubt but most of the times the coin would simply crash so badly that it returns me to square one. The losses were painful, but they taught me lessons I feel are worth sharing, especially with other beginners out there threading the same path.
Here are the lessons I learnt
1) Don't blindly trust signals, take your time to access and verify it.
2) Do your own research(DYOR), coz it gives you confidence and control.
3) FOMO and panic selling are dangerous. Rather be patient and disciplined.
4) And lastly, Don't Invest more than you can afford to loose.
