Imagine trying to sell the idea of someone using some digital currency to buy a Coffee which is $5.00 and they're going to have to pay 10 percent (.50 cents) To the network in order to get the transcation to go through in a timely fashion (still not instant)
This person is simply going to ask why can't they use their credit card, debit card, cash, or anything along the lines of that which is going to be an instant done and finished right there.
Point accepted. The average Joe and Jane prefer to use cash or debit/credit cards to do their shopping. Even many crypto traders and investors prefer to hold on to their bitcoin as use it as an investment and not as a currency. But there are few people who promote bitcoin as a currency to outsiders.
I do feel that in the next 10 years or so, we can see a change in this trend and more new people will join the bitcoin network and do more transactions with it.
It will happen but it will take time. Whe I first discovered bitcoin, I didnt know it was very useful until i notice many posts that sharing their profits on bitcoin. I am also an ordinary citizen so its possible.
