Well i like this one.. here is a way you can get up to 8 bitcoins for referring just one person.
True flip is a blockchain based lottery system.. and currently the jackpot is 400 bitcoins!
When you refer people to the system, if they happen to win you will get 2% of their winnings.
If they win the jackpot, this is 400 bitcoins! 400!
Your referral commision would amount to roughly 8 bitcoins, just for referring one single person.
If you happened to refer hundreds of people, the chances of you winning a large sum would be fairly high.
You also get paid 5% of tickets your referrals buy, on top of a percentage of what they win.
So i am on a mission to refer as many people as possible.. and you should be too.. would be nice to wake up with 8 BTC in my account one morning.
