I recently reduced my portfolio to just EOS and STEEM.
Why? One is the future of the social web and the other is the future OS of web 3.0 (and covering all the rest, apps etc) - I realized, that there is no valid reason for me to own any other coin at the moment.
Since I don´t believe in the "currency" part of crypto (as in: you pay for offline goods and services with digital currency), I don´t have any need to invest in something different.
