Crypto is definitely a good alternative if people don't trust banks and you can also use it to pay for goods. However unless crypto is accepted more widely in society as a payment method, it isn't enough to overthrow the current system. However I think it will get there over time as more people adopt crypto.

I don't even think Crypto should overthrow the current system, I believe people should have that choices to always go for whatever option they'll chose. Eventually or Inevitably Crypto would definitely make the rounds, it's intertwining with our everyday lives.
