I am proud to say I have used crypto to buy a physical souvenir, a steam game, and a yearly subscription to a service.
I would gladly do that more if they allow me.
The best "comparison" I can make is this: - I buy random shit online every now and then, also from Amazon. That one souvenir I got for me and a friend was about 40 dollars worth, and I paid with crypto that time. - I buy steam games maybe one every 3 months? So buying that one game with crypto is a small percentage, yes, but also probably the next game I'll get will also be with crypto payment, so it will increase the percentage slowly? - For the service, I have paid maybe 15 dollars for similar services in my life. That one that accepts crypto is also the best one I have found yet, and to that I have paid about 80 dollars so far. So for that, the percentage is up there, and I'll continue paying them that way!
His experience was that basically nobody who asks for it are asking because they are potential customers, but because more sites showing the bitcoin logo means their Bitcoin portfolio goes up because people start believing it's real.
Asking for cryptocurrency options is basically market manipulation, not an actual request.
They waited long enough for regulatory clarity on crypto (and still are waiting for other rules to go through) and they have already deployed their offerings today.
So there is no 'big problem' and those companies are choosing the cryptocurrencies that will survive regulations.
