And now some politics...
   Here is why Bitcoin Cash (BCH) Is The Real Bitcoin
   It is the original bitcoin
   It was hijacked from Gavin Andresen very surreptitiously by Adam Back
   (back in the day, Adam and I worked on hashcash and digital
   cash-related projects) with his [1]Sidechain proposal. It was a "Trojan
   Horse" and together with the help of Blockstream, Theymos and the Core
   developers the process was completed. We, the original community, have
   finally regained control of the Bitcoin project, except that we have
   lost control of the name. This position is about to be redressed.
   It does not have Segwit.
   If you look at a Bitcoin file as AD. A being the address and D being
   the data, Segwit removes the address portion A, It is reduced to a hash
   and the original signature is discarded after it is verified. So if
   your "fingerprint" is the hash of all your signatures, the signatures
   are discarded after being checked, and only the "fingerprint" is kept.
   This is in effect what Segwit does.
   The signatures are stored on another chain, but not the main chain.
   Some nodes will keep signatures, some only keep partial records, some
   will discard them entirely. If you ever need to refer back to the
   transaction to check on the signatures all you have is the hash. "The
   fingerprint". Satoshi's original design of bitcoin being an unbroken
   record of signatures is violated.
   It allows for unlimited on-chain scaling.
   A clear example of the disastrous effect of limiting the blocksize is
   the state of BTC now. The mempool is huge and getting bigger, fees are
   "over the top". Their intention is to push low fee transactions to side
   chains and the lightning network. These solutions don't exist yet.
   The Core developers bought themselves over 2 years delaying and
   obfuscating on chain scaling, and yet have no working solutions.
   Meanwhile the user experience gets so bad that many users have sought
   other alternatives to transact. BCH in the meantime have mined an
   [2]8MB block.
   It has more client implementations
   BCH will have Bitcoin XT, Bitcoin Classic, Bitcoin Unlimited, Bitcoin
   ABC and more. Each with their own development team but all operating on
   the same chain. This diversity increases security, innovation and
   development of the whole ecosystem.
