I write this mainly for $800CC ERC20 Token Holders, but everybody can do this earning method actually.
See 800CC Smart Contract
1.First method is free and simple : predict price of Bitcoin on 7 November 2019 and you win 250$.

Example:
2.Second one is a try , I do not guarantee that it will work but it cost you 2,3 dollars to try.
What's about ?
Last month i deposited into BlockFi just 0.0321 ETH and at the start of this month , I was surprised by seeing into BlockFi account 0.0059 BTC which I completed withdrawn to my Coinbase account and cashed out.
What you should do?
What I want you to do is to make an account on BlockFi and deposit 2,3$ worth of Bitcoin or Ethereum maybe this month will be the same.
Register here, deposit and let's wait the end of month , maybe we will have a nice surprise !
PS: BlockFi main use-case is that you can earn 6% interest on your crypto and you can even borrow USD.
Over and out,
