the use of bitcoin will not be entirely accepted by the public for currency but to be an investment asset is very possible, so we only need to see the development of altcoins that will be directly in contact with the public for their needs, such as in web3 for example or other assets that can be connected to blockchain technology. I quite believe that all will not be disrupted, only certain parts can be integrated.
You're right to some extent but the public if not willingly then unwillingly , due to increase in transactions and development of the crypto world will be bound to accept it.The banking system when introduced was not accepted by the public on a large scale then Ultimately due to wide spread and quick development it became apparent.I think the same is the case with Bitcoin and other crypto currencies they have to be accepted due to increased interest and demand.
crypto market is revolutionising very fast and they are being used on a large scale in freelance sector for transactions.Itll increase more when the awareness will increase small venders and business owners will definately use it.
I feel like it is also about improvements on it as well. Imagine banking system being something similar to what it was back in the day, in this world, do you think people would use it? Like you write a paper to a bank, deposit your money, get a signature, then you take that money, go to a shop, you give that money, the shop owner calls up the bank, gets approval, writes something, you both sign it, then the shop owner goes to bank, shows the paper, and gets their money if they want to.
All these takes a huge time, and right now we just use a credit card or wire transfer and we are done, takes less than a minute. This is why I honestly believe that the innovations on blockchain that will improve bitcoin could make it spread even further, just like how it happened to banks.
