And that is the key. We know that cryptocrurrencies will take off, we just arent sure which ones.
My holdings basically are BTC, LTC, ETH, STEEM, and BTS. I feel very comfortable with that at this point. I also have a decent stake in a coin I mentioned a few times that is out but having the platform around (website, wallets, etc) updated. It passed the trial phase, now it is being fully automated.
I feel I have the basis for continued growth the the big three (BTC, LTC, and ETH) and the potential for explosion in STEEM and BTS.
Since you are invested in the top ones you can always play around with the upcoming ones I guess, as long as it's play money, life's gotta be fun too
