I think that the question consider on this post it's wrong, cause after 1 August there will be NO more original Bitcoin, we can talk about what will be the stronger coin, Bitcoin Cash or Bitcoin Segwit, but treat one like the original Bitcoin without any base... If u understand the consequences of segwit, in the sense of changing bitcoin protocol, you cant say anymore original Bitcoin.

PD: Another thing would be discuss about wich is the most similar to the original proposal of Bitcoin...
