To be fair, there are few restaurant and merchant (who sell voucher for restaurant or online food delivery service) which accept Bitcoin.
Businesses accepting
BTC doesn't mean automatically customers will spend their coins, that's one of the problems, we have more and more business taking payments but the usage...Let's assume you've just woke up, you see bitcoin skyrocketing, would you feel tempted to use your LN wallet or your usual CC to pay at the next gas station or store?
It's like a damn paradox, people don't spend because few businesses accept and few businesses accept it because people simply don't spend, one quick look at the half-full blocks and it's clear the usage isn't there. Of curse, some have migrated to LN, but still, I would say that over 80% is not 90% of the people who hold bitcoin right now have no plans of ever spending
BTC and just hold for 2-3-5 years and take the profits in $. Anyhow, it is what it is, that's what a free world looks like, everyone is free to do what he wants with his money, be it $ or
BTC.
