No Bitcoin is the real chain.
One is BITCOIN
One is Bitcoin Cash (a new altcoin, not the REAL BTC)
There was the original chain which is Bitcoin.
Then the core devs failed to understand the purpose of Bitcoin and limited the block size to 1 mb. Hijacked the discussion, forced the intelligent devs to
fork their coin from BTC. Then they implemented new code which fundamentally changes BTC from a currency to a settlement layer.
Both are forks from the original Bitcoin. Segwit, Cash.
