Perhaps my biggest mistake was to underestimate the potential that had ethereum to become the second most important cryptocurrency of all, because for a long time I was aware of the success of its ICO and the great potential for growth that offered for those who invested in the project, but I did not take too much importance.
But even afterwards, when it came to the market, I had the possibility to buy many ether at $7, but since I still did not believe in the project, I sold my ethers at $10 thinking that winning 50% was a good business and that a correction would occur soon.
I'm still waiting...
My biggest regret was when I was very impetuous to sell my coin thinking it was high enough. I missed the important part of planning for selling crypto. From that mistake I learned that I must have an end-game, and stick with it. No need to rush things, it would lead to wasting the effort and time. Additionally, I regret when I was not doing my own research and too dependent to listen from the experts, waiting for their go signal when to trade or not, resulting in so much trouble and losing a lot of money. Mistakes are part of life and success, learn from it and move on.
