Best is to find free ICO like Marinecoin does. Check out the airdrop they are doing right now. MTC has a machine to machine, self sustaining system. Check out their website:
https://marineco.in The community is still small but growing. Their airdrop is based on artificial intelligence and super easy. It works with proof of promotion. It could really go big. Since it doesn’t cost anything it is for sure worth trying out. You will get 20000 MTC for almost no work. It is done in 5 minutes. And you can also repeat the airdorp every 24 hours. Until the MTC runs out.
