Now appear comfortable tools and products that allow to spend crypto in different shops.
Also now cryptocurrency is actively used to buy NFT.
Can you mention what tools are supported by many stores for cryptocurrency needs at this time ? because for me cryptocurrency is trading digital currency which is very easy to run by anyone who understands it and I have not seen any store that supports cryptocurrency activity in my current environment.
I guess one of it is bitrefill. They're not just tools but actual services that do offer other services and products in payment of bitcoin and other crypto that they support.
As you've said, it's a digital currency so it has to be spent. Whether you're spending it on trading, that's fine or the same as bitrefill then that's okay as well. That's the sole purpose of it as an alternative payment to the traditional payment methods we've got.
