patient, in the next few decades, I believe we can use Bitcoin to shop in supermarkets...
You can order crypto debit card and pay via it everythere. This will be much faster than waiting for a mass adoption
this time, using a credit card/debit card today is certainly much easier and faster while waiting for bulk adoption.
It will take time actually to have a massive adoption of bitcoin. As the current use is mostly debit cards which is the fastest transactions. Also, the volatility of price of bitcoin which is really expensive and not advisable though. So Imo let's see in the coming years if there's a massive adoption in crypto.
