What this thread shows is that only bitcoin is worth investing in, and if you want to bet on any altcoins, do it with a small percentage, I would say a maximum of 15% of your holdings. Bitcoin is a safe bet, altcoins are more uncertain, and if you want to bet, I wouldn't get hung up on CMC's top ten, it's almost better to take one or a few altcoins that you think can multiply by a lot in a short time, like 50x or more in a year at most.
