Well GRR 3 years is about right to build a full eco system and block-chain usage with clients on board. What is under performing? no promises were ever made, It would still be soaring on Trex no doubt if not for the 51% attacks. (that dev forked out 80k to cover losses for users)
So you could throw your money into ICO's that at best 2% will have achieved there goal in 3 years or just hold onto one that has done the hard work and is in final release testing.
requires a little patience but really what else is such a good buy in the market at the moment you would tap out before the final hurdles
