And it's not just bitcoin. I know of Tapcoins, for instance, being accepted in hotels, restaurants and bars and I'm sure there are other currencies out there on the same track. Hopefully we hit adoption soon, as that's the future for this industry.
Adoption is something that would in the long term kick in as that is something that cannot be avoided. It is a gradual process and we are going to see more merchants and companies in the long run trying as much as possible to adopt the usage of cryptocurrency as a payment method just as we have few who are already doing that.
At least I know of some Automobile industries in the US that are now accepting bitcoins at most, and I believe as time goes on, we would get to see more of this. It is just a matter of patience and optimism as we will most definitely get there.
You right adoption will require a very long process because in some areas not everyone wants to accept a new development and technology. Moreover, the rules that bind them do not allow using crypto. of course adoption will be increasingly hampered. but you're right as time goes I'm sure there will be more offline or online merchants who accept it. because users will continue to increase
