My hidden gems for this year are 3
i know nobody is going to pay any attention..but still for me they are gems!
The first one is HPB, they said they want to make a scalable coin similar to ethereum for dapps and that they will achieve their target with hardware accelaration chips that they will provide to their nodes..every coin wants scalability but at least they can provide information on how they will achieve it. They have announced official partnerships with okex, wbg(world bank group), Unionpay smart ( a kid company of Union pay which is handling data of Union pay and not transactions dont be confused). Even if the main net is not here yet we cant deny their partnerships which in my point of view is giving them some extra + for the time being.. Mid marketcap around 70 million $.
The second one is TTT trustnote, this is a coin using DAG similarly to byteball not IOTA or NANO and by this i mean that it has fees. They plan to implement easy to use smart contracts and make the coin minable as for now it is not. Low marketcap about 8 million $.
The last one is XXX adultchain this is a coin for "adults" similar to coins like vice ( or verge muahahahah), it is a masternode and pos coin (with privacy as well similar to pivx as it is soft fork of it great plus for adult industry
) with their own platform, this platform is a marketplace to buy adult staffs and to hosting cam shows..recently they had girls like brenna sparks and scarlet raven for testing it. Very low marketcap about 700.000$.
