There are a lots of stores that are accepting bitcoin even if it is an offline and online transactions . They provide bitcoin holders and users to use there bitcoin in a hassle free.
if bitcoin legalize and much offline stores accept bitcoin as payment, we will see bitcoin price could rise alot.and now much ico developer build project that make cryptocurrency accepted on offline stores.
Of course, that is something that is bound to happen and once we see the price skyrocket based on mass adoption and usage, there is every chance that we will get to see some balance in the market, which will bring about less volatility, and by then, I am pretty sure that less volatility is something good, considering the fact that a lot of merchants all over the world, will not have a problem accepting it as a payment method.
So far, we have seen a lot of companies and merchants skeptical and we do not have the infrastructure yet with respect to scaling, that will really make it easy to see mainstream adoption any time soon, but it is worth waiting for.
