My most valuable lesson of 2018 is not to be greedy and try to take profits. Especially when some coins made X 30 or more. I didn't do it then and now I'm a little disappointed that I missed a good opportunity and wasted time.
Such crazy things really happened especially in the time when ICO really made many lucky investors to bag out huge amount of money,
Though not all are lucky just how things happened to you, either you missed the fun due to wrong perceptions or you got greedy thinking to push for more.
Those are things that you'll going to remember and learned, since you are still here, for sure you wanted to do different things and try to make sure that you'll going to take every opportunity that you have to be earned and manifest success from this business.
In 2017, I still had very little experience in dealing with crypto investments. At the time when $1k invested in one of the tokens during ICO brought me $36k, it seemed to me that this was just the beginning and the price of these assets would only increase. However, now their price is barely $ 300. That's the price I paid for my experience.
