According to Messari's OnChainFX data, all of the 134 cryptocurrencies listed in the 2018 ROI data show a negative return on investment. Although the collapse of cryptocurrency in 2018 is undoubtedly uncomfortable and unpleasant for some in the community, there are some who believe that this is a signal that prices have bottomed out. In 2019, the price of more than 50% of cryptocurrencies was even lower than at the end of 2018. Many investors have a prejudice that it is a more cost-effective deal when the price of an asset begins to fall. Their idea is that they can get a "more favorable" price in the next buy order. While this idea applies to consumer goods, the same idea can be fatal for cryptocurrencies.
