I think making BTC super expensive is not Satoshi's dream. Current chains became gambler's tool for speculation. Only after the price collapse, people start to consider its function.
BTC has no function, it is slow and expensive to transact. We need to toss it on to the garbage pile of history and use BCH.
At the beginning of bitcoin, there are much more Opcodes and have complex functions, but for safety reasons Satoshi canceled a part of these and set 1MB limit temporary.
I doubt it, he was reaching out to people via email to try to get to know them so he can inject himself into the project to control it. Epstein had no clue what Bitcoin was.
Though he doesn’t programming bitcoin, he invest the groups at early years and has large influence on the block size problem. He must know a lot about bitcoin and get benefit from it
The market chose BTC Core be the bitcoin rather than BCH, at least for now. And the Core team is the successor of the bitcoin code, even if it contradicts Satoshi's Vision.
