Hi Everyone,
I want to show you very easy referral campaign from famous Okcoin exchange. You must register from referral link and your referral and you must pass KYC verifiaction Level 2(needed 5-10 minutes). You must deposit 100 USD(105 with fees) and after this buy any crypto(do not deposit crypto at first).That's it. You and your referral will get 50$ bitcoin. You can withdraw your deposit 100 usd, but bonus will be locked 180 days. I have already tested it and works everything 100%. Good luck everyone! 
This is my referral link:
www. okcoin .com/join?channelId=600126591 
Feel free to ask questions. 

P.S. Remove spaces around "okcoin" , I added them to link because I am not allowed to insert links.
