Crypto currency sector is similar to cellular ( mobile ) phones development stages.
when I joined crypto in 2015 , there was only Bitcoin and few more coins. Even ETH ico comes later. That times were same using Motorola 5200 in 1994 for call only. No utility, no security, no sub features.
In 2017, market evolved. Such as using Motorola I1000 to Startac with radio, internet browser, VGA camera... market filled with many projects which offer wide range features. Frenzy times in mobile phone sector and boosted sales figures ( remember 2017 bull run ). x100 in that times...
2018 and 2019 were similar to last times of conventional mobile phones before Iphone and Androids come. try to survive and offering "not different " differences.
Now we are near to threshold for who will evolve and who will be in the history. Who invest in the cow will be the new Samsung and who invest ro milk will have similar fate with Ericsson or Nokia.
