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,
Most traders make a whole lot of mistakes similar to this and sometimes it may be due to peer pressure from friends and sometimes it's due to the fact that you're on the verge of making it quicker, every mistakes is a room to learn and a more reason a good research should be done in respect to that. Sometimes it's the fear of being left out when everyone is buying a particular coin that makes one takes up the decision that end up as a huge mistake.
