I'm asking to almost every store that I generally go to accept BTC and main altcoins.
It's not really easy to implement that kind of payment system in every country, that's why it is really hard to spread. We need more innovations.
Correct, it's not easy for those store to adopt the system as they needed to be familiar with how crypto works and with this sway from the price its even adding the doubt from the business community to use it as a platform for their business transactions, maybe after some years when more people already understand and knew how to use this system, maybe market will follow we just needed to help the community to fully understand and embrace this innovation.
