Your question had to be fair enough if this wasn't the bitcointalk.org forum. Most of the times, I've seen users (Not all of them) are trying to belittle newbie users by asking kind of questions with the purpose of ________.
In the fact, at the present, you aren't even a purse.io user. that's why you've pointed out it as,
We currently have Purse.io that as far as I know provides the same service
Which part in my statement did I "belittle" OP? You know what my statement is called? It's called constructive criticism. Look it up. Seriously. It doesn't take an expert to see that. 🤦🏻♂️
Also, I was a past user of Purse.io(not that it actually matters in the first place). The reason I included the "as far as I know" part is because I'm not 100% sure if they still provide the same exact service, as they removed the option to sell products that's not on Amazon.
These places are not actually cryptocurrency. They are using a 3rd party that instantly converts the bitcoin t ofiat. I would be more impressed if merchants were willing to actually hold bitcoin which would show a great faith in the entire ecosystem.
While true, this is a decent sort of "band-aid" solution. Having the option to pay with BTC is always good whether or not Amazon actually accepts the coins themselves.
