At that time, many lost their investments. After good growth in the second half of 2017, altcoins lost 90-95 percent of their value the following year. This was probably one of the reasons for the long two-year bear market for cryptocurrency. Therefore, there are a lot of such stories. This lesson must be remembered. However, this situation is unlikely to be repeated with certainty in the future. Cryptocurrency is developing rapidly and market participants are gaining experience. Now they no longer invest in any new projects, as it was before. Therefore, now the most promising altcoins are growing in price, it is in them that investors are investing, and the garbage remains lying.
