What if Bitcoin was reimagined today, under modern cryptographic assumptions, using a principled minimalist architecture designed for long-term auditability and zero-trust adversarial environments?
Get into the future and leave the past stage of bitcoin. Bitcoin of course can't be reimagined because it's absolutely nothing possible, why give yourself false hope or ridiculous assumptions when you can be out there gathering the least you can gather?
Do you want bitcoin centralised? for the reimagination, of course the US government will want to be the creators of bitcoin and be the overall entity in charge of the demand and supply of bitcoin.
