What I'm trying to understand and defend against a lot of the mass skeptics is this exact question - Would you use bitcoin as a currency if it was possible?
..
"if it was possible"... then why not? Besides, I already using it at some of the services.
But for a cup of coffee, how much the cost of it we are talking here? Is using and paying with BTC does make sense here or just pay it instead with some few bucks on our pocket which is for me way faster and convenient.
Will treat it as an alternative payment since on the other hand, I have other payment sources
e.g fiat salary, credit cards. As much as possible, I will consider paying with crypto only if I'm run out of options.
This is a good post and asks a lot of the important questions that we need to consider if BTC was to truly become mainstream.
One of the main issues, why this will likely not happen, is the concept and premise bitcoin's blockchain was built on. Bitcoin was meant to replace the overnight wire transfers and be an easy way to send money overseas and this was combined with the purpose to be something to rival the centralized system of banks. Bitcoin was never made to be used to buy a coffee on your morning commute - there are other projects/coins that are purposely made to do this. Pundi X is a good example of a micropayments system and its blockchain is developed around the idea of using their tokens to pay for small items.
