I feel Gems Protocol is a solid contender for one of the best upcoming ICO's.
Gems Protocol is a decentalised version of Mechanical Turk.
It basically solves all the pain points of centralised system, cutting the central fees out of the system. Plus easier interface and decentralised payment systems.
One of the good usecases of cryptocurrency. I am looking forward to use its platform.
Founders Rory and Kieran already have a success under their belt Gifs.com. Also Rory has Theil fellowship which aint easy imo. Advisor is cofounder of twitter which is big.
I hope they expand the team and include some blockchain experts, they already have a few not mentioned on their site.
I strongly recommend that you join gems' telegram and visit it's website.
Finally someone who mentioned this nice project

. There are a LOT of ICO's out there and it's a jungle to say the least. But I feel GEMS is one of the most promising projects out there. It basically creates a new ecosystem around so-called mechanical turks (which are microtasks needed for any business where a human brain is needed). Amazon currently runs a program like this, so one can imagine how huge the market is. Read about it and you will thank me later!
PS: I forgot to mention the great team behind this project. Very cool project with very active community!
