You're basically saying that someone would pay 5$ for a product while paying with Visa instead of paying $4 with a Mastercard because Visa is more popular and has more users. Why would you do that?
I bet that most people couldn't even tell the difference between popularity and fees on Visa and Mastercard. I sure cant! Because it depends on the bank that's issuing it to you. ~
Point being, most people can't tell the difference between fees on different blockchains either. They just see one coin having expensive withdrawal fees (they use exchanges) and use another one.
People don't care about Visa and Mastercard (debit) because they don't pay a fee for it at every purchase, I don't even pay a monthly fee for example, neither for the card or for the bank account.
For crypto, they care somewhat because they see they need to pay x on a y transfer, if fees would have been like Visa and just taken out of the final product, much like VAT is here things would have been different.
Bruh... not everyone has extraordinary wealth, using it repeatedly will certainly drain your balance too... it's true, I can't blame everyone's choice... but choosing something wiser in my opinion is the better thing here... like people who really feel that transaction fees are too high will certainly consider other options, such as changing to another payment method that is more friendly to transaction fees...
Yeah, but that has nothing to do with popularity, Doge is less popular than Bitcoin but it is cheaper, at the same time for someone who has only ETH that doesn't mean a thing since he will have to pay anyhow to switch his coins into that altcoin and just that fee might be more than what he is saving.
