Am still trying to think of other easy ways to spend btc if not through payment system, because I know btc is not physical, it is digital, I don't know of any btc card yet where you can spend your btc directly to buy anything without any third party,
Eventually the only available option still fall on the payment system at least for now, and I don't think kyc is such I bad thing, I already use my bank card to buy online often times, so I think this is the only way to spend crypto for now.
Bitcoin was made for peer to peer transaction so for you to spend it the other end should be able to receive bitcoin by any means. I don't think we are near to be able to have this, look how people are treating bitcoin, it's not even a currency to them it is just a mere investment, in and out profit maker. Don't get me wrong about this, no one will ever spend bitcoin if you think of the potential of it in the future. There are already platforms that has integration with bitcoin, that's a fact, yes, but have you seen the traffic? have you seen the number of user? it's very low, so I don't think it will be a thing for a few couple of years more.
