With all the late fuzz about cash banning, the digital euro and financial surveillance it comes down to this nowadays: IS THE COIN PRIVATE OR CAN ANYONE SPECTATE RIGHT INTO MY A$$HOL€?
If the answer is "not private", it's a traceable gotohell-coin. If it's private and fungible take my money.

Just think about protocol evolution from http to https... imho same will happen in terms of public ledger and private ledger.
