I'm looking into this new project called MarineCoin. The community is very active and the way they're combining AI with Crypto is very interesting. They're offering 450,000 free MTC if you go to https://marineco.in/ico
Do you agree this project is worth to keep an eye on?
I think these coins are the most promising and the cheap coin. You could research on them.
