I agree, probably ETH is the most option to get the best returns, however there also interesting projects that have real products and worth mentioning, for example FLO (they have launched 2013) and inSure token that allows you to be insured from the losses on your crypto portfolios. I already acquired some on CREX24 (was lucky to catch the price drop).
And also completed some bounties.
