My bet is Zenon (ZNN). No ico, seed rounds or VC funding. Low supply (6+ million max supply). STRONG probability that it is backed by Square Crypto, which is Twitter CEO (and BTC proponent) Jack Dorsey's company. If that is the case, I think 100x is possible. Whitepaper will be released next month, which will be peer-reviewed (a rarity). Right now it is a fork of pivx as a placeholder until mainnet, which will come in Q2 this year. I've linked a medium article below which lays out the highly probably (imo) Square Crypto connection. DYOR as always.
