BTC has already become the best long-term investment asset. Adoption has to happen
There won't be any adoption left if bitcoin is seen as an asset and a money making machine. Bitcoin can only continue growing as a payment system which people use to reach financial sovereignty. That's the "technology" that matters here.
the legalization of BTC (WITHOUT KYC)
That's kind of a contradiction. Governments are all about control and surveillance. They won't legalize bitcoin without having some degree of control which is where KYC comes in.
