is it possible that bitcoin will be accepted in local stores, shops etc. since transactions are to slow and customers have to wait until their transactions are verified. And nobody wants to wait.
Can transactions be seeded up to save customers time or any other way to use bitcoin at local stores.
Well of course. That's one of the points of using Cryptocurrency so you don't have to pay cash on the table and instead use BTC while Sitting behind your phone or pc ordering what you desire.
Transaction is fast if you choose to pay a higher fee and for sure even if it's slow sometimes, it can still be possible as for sure merchant will make a way to attract more market to profit. If it's possible in online stores then it will be possible in local stores.
Yes of course it would be possible for local merchant stores to accept bitcoin but it would not be practical for most.
A online currecy should be used online.
