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.
My biggest mistake was following the advice of my parents to not invest in Bitcoin and instead save my money in us dollars. I've always been the one who has been suggesting others to buy Bitcoin, including my parents but no one listened to me and I regret that I listened to others, I thought that adults were wise and more experienced but I was wrong.
Btw lessons that you learnt are good but I don't agree with the 4th lesson. If you dont' invest more than what you can afford to lose, then you'll never make enough profit to have a good life. If you invest small, you'll receive a small profit. Maybe my advice is not good for everyone but in tough times, I invested in Bitcoin more than I could afford and it paid back well. Btw I'll never invest more than I can afford to lose in altcoins that I have no idea about.
