I used ETH and NEO to invest in ICOs. Also I played CryptoKitties on Etherium blockchain and I'm playing doperaider on POA now. But I still thinking there is no mass adoption of all blockchains maybe because of bad usability and scalability.
The scalability issue is a problem..
Bitcoin NG partially fixed the problem, and possibily sharding can fix eth in a couple years...
But the scalability of eth already became a problem during last winters hype.
At the moment i think there are only a few blockchain platforms that could scale 50-100x's ETH ability.
