Actually I am currently holding a number of tokens as a result of joining the bounty, and I will save this until at least I return to ico's price because currently the price is still decreasing after being registered on the exchange.I realized that in the long run many of them will turn out to be non-performing obviously because many are just start-ups and many do not have the product yet therefore no revenues to boast with. Not to mention the fact that problems can come up and even the team behind can find themselves at war with each other (hello Envion and Tezos) resulting into big dumps for the tokens. I think the best way to make good money in cryptocurrency is and will always be trading but then this is not suitable for everyone as this can also be risky. Right now, I decided to only hold tokens that I am sure can really be worth the wait and the patience.
