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.
Yes via bitcoin credit/debit cards, Bitcoin blockchain is the settlement layer, however for purchases that you want to be instant, you will most likely use a 3rd party bank card, which will probably be issued by banks in the future, once they embark Bitcoin.
This way both banks and cryptocurrencies can survive and actually cooperate. We only need to get rid of fiat money, but the other tools can stay, since they proved themselvesto be easy to use.
We are going cashless anyway, the question is, will you have Euro/Dollar on your card or Bitcoin?
