It will take more time for you to realize that BCH has fundamental flaws -- https://hackernoon.com/the-ethereum-blockchain-size-has-exceeded-1tb-and-yes-its-an-issue-2b650b5f4f62 (Covers ETH, EOS, BCH and some others)
It also should be concerning that Roger Ver hasn't taken all of his BTC and converted it to BCH.
Its easy to prove - just show us the wallet addresses and the entries in the blockchain where it was transferred, along with the corresponding transactions on the BCH chain where it was put into a BCH wallet.
But Roger will never do this - he even has admitted that he still holds Bitcoin. Wonder why?
If his personal project is so great, what is stopping him? Is he simply waiting for others to be the bag-holders before performing a large exit scam?
Time will only tell -- and a lot of money will be lost in the process.
