IOST currently has a great referral programme going on, which gives you 68 IOST for every friend you refer.
The great thing is that it is already listed on CoinMarketCap and currently trading at $ 0.08. So you basically get around 6 $ for every referral.
If you want to sign up I would very much appreciate if you could use my referral link here:
