Bitcoin launched with huge blocks (32MB), then it was set to 1MB to prevent spam. When time came to increase the blocks bad actors came in and crippled the network to make sure it cannot be used as a payment system.
The point is BCH is the real Bitcoin and BTC is a hijacked cripple with a completely altered design. Bankers pumped the BTC price so people would think it is the real Bitcoin which it is not.
