I love how altcoins and Bitcoin moved forward in 2017. A terrible profit margin was made when Domain BTC.D dropped from over 80% to around 50%. That has led altcoins to increase in capitalization one by one. At that time, there were not as many altcoin projects as there are now.
Currently, there are about 10,000 altcoins, so the ability to create a strong mass increase like in 2017 is more difficult, not to mention that the BTC.D domain is below 50%.
