My question to us right now do you think Bitcoin will eventually erase the commercial banking sector???
Bitcoin can become successful on annual basis but they cannot completely erase the use of banking system because still people are in favor of using bank. Most of the people are not familiar with bitcoin so I think acceptance of bitcoin for them will be difficult at start as old people rarely trust digital money and digital investment.
Bitcoin was considered as a currency in past but now you will know that instead of using it as a currency people are using it as an investment tool and I think in future it will just be use to increase the value of cash.
I don't understand what you mean by annual, but Bitcoin has been with us for more than a decade already and it's proven to be a good investment or store of value and even hedge like in the pandemic wherein I believed some of the rich and wealthy people put their money on Bitcoin so that it won't loss any value.
But as for making the banking sector obsolete? No, that's not what Bitcoin is design in the first place. It was originally for P2P and a payment scheme. It's that people in early days found out that they can exchange and trade it with money and make profits. But it's good to see that some banks are cool with Bitcoin right now, not all of them but a small percentage and that is good enough for us.
