I have 11 more cryptocurrencies in my portfolio, in smaller percentages, like Ripple, ETC, BTS, DOGE, Digibyte etc.
Basically I define the percentages and I make monthly increments keeping the percentages. So if a currency falls in price I buy more, and if it rises too much I buy more of the other currencies. It is the same strategy that the holders use in the traditional stock market
How to study each cryptocurrency takes time I started with the best known ones, and now I'm starting to study the less popular ones.
Steem I started now but I find it promising. I have to know a little more to include in my portfolio.
EOS is in the study queue.
Thanks for sharing your point of view :)
