I think as more kyc and aml regulations come into effect this will bring about the rise of digital transactions. In Greece for example now more and more cashless payments are being made, especially in restaurants by law to avoid the V.A.T tax evasion that was rife in the country until this new law was implemented. Also crypto enthusiasts and libertarians on the other side like to hoard and amass the more individual tokenized assets and decentralized coins like Bitcoin and Monero to take a stance against the general powers that be, like our current fractional reserve banking system, which have impoverished generations of people and have created a prison planet of slavery. There will be more cashless societies in the future but how fast cash will disappear, that, no one has the answer for yet.
