Yeah in these things iare hard to know which currencies you should hold and how much %... In the end it all comes down to which do you see closer to happen, steemit getting to $100 someday or Bitcoin to $150.000 (both multiplied per 100) as mass adoption comes along.
Personally I like to diversify a little bit though I love steem :)
diversification is the best thing to do. i buy up-to a million of some coins.
