Imo there isnt any future for non regulated or non traceable crypto currencies.
Like the saying goes,(where there is a will, there is a way)...from the current financial scenario globally, crypto cant be stopped,....
We all just got wind of paypal adopting crypto,that right there, is a major trigger/indicator to whats ahead concerning the relevance of crypto Globally...(imagine what it took for paypal to get such operations to fruition/into reality)...and we all know paypal is Global.
Inrelation to the above, systems would evolve/services would emerge/ a ready market already exists that would circumvent all efforts to make crypto traceable..the basic DNA for crypto was: No control,Non regulatory,purchase freedom,decentralized etc, and based on all this factors..crypto is here to stay and whatever side you choose,Crypto Is Symbiotic..
NB: over decades before now FIAT went through situations where controls,policies etc were enacted to curtail and control currencies, but yet we had and still have ways of moving FIAT,trading purchasing, across the Globe anonymously despite decades in the making..
(Long live Crypto Anonymity)...
