Welp, that's too much diversification. I would eliminate the other coins with what I see to the market right now and put it to other coin. I'll take the quality than quantity which is better because the market looks starting to get healthy and pump again these days.
You are probably correct. On the other hand, the op's list could serve as a kind of lottery ticket. Some of those coins are solid ones to own, while others are very speculative. It's the latter which could prove to be big winners, and since the amount of money he's putting into them isn't outrageous I would say his choices are fairly good.
It's really surprising that you couldn't hold any Bitcoin which is the best for both investment and holding
Yeah if it were me choosing how to invest some money bitcoin would be my first pick. Some traders want to gamble on the chance that there are some overlooked goodies out there in the altcoin market, which there could be. I have a feeling that most of the ones on that list aren't going to outperform bitcoin, tho.
