Most peoples' answer to this depends on how long they've been in crypto.
If I was a brand new arrival absolutely not. Why would you? There are options that are non volatile and less hassle. Obtaining your crypto would've been a grind.
If you're sitting on a pile of free gains then why not? Time to realise them by buying some junk.
The latter are in a minority so I don't think any such place would thrive. And most of the time the existing places like this charge you more money for the honour of paying with crypto with much worse choice. I'd never take a shittier deal because of some sentimental attachment to my payment method and anyone who does is a numpty.
That is right, but I think many people will still do and actually use it to pay for goods and services just for the sheer convenience and ease of it. It is really an easy call for some, especially those who have been so used to using their credits cards. Moneyless transactions have become the norm these days, and for someone who has a substantial amount of Bitcoin to use, especially when its price becomes a tad more stable, it would be easier to use it truly as a currency like it is meant to be used.
