- Referral program, which is probably the hardest as everyone knows about Coinbase and have an account by now.
- Learning about Stellar lumens or 0x and inviting friends to learn about it as well.
Well, not everyone has the coinbase account. Still more than half of the humanity does not know about bitcoins or crypto currencies. This referral scheme still has a lot of potential but we need to find out new people who are totally New to Crypto . We of course cannot found those people on this forum

We need to spread the bitcoin to our near and dear ones, to our friends and family and ask them to make the account on coinbase. Also there will be no earning, if our referral does not buy sell the currency on coinbase.
