My previous mistake was not doing research when I invest in ICO or buying coins, I was only interested in telegram discussions or chat rooms so that I lost money and even got a scam, now I will research before investing.
When the market is growing and most of the projects successfully raise funds, you do not consider it necessary to do additional research of various projects. This mistake cost me money.
Mistakes are truly undesirable when it comes to money investing. Of course, it's not possible to avoid every single scam but project research is a strongly needed option for an investor.
