The government and the banks won't allow the system of digital currencies to rule the world. Even if digital assets are more efficient, low cost and more secure, they won't allow it to happen simply because they have no control over it. And in the future for sure, cryptocurrencies like bitcoin will be the most effective form of doing financial transactions.
Banks really disagree with the existence of bitcoin. they consider this to be their competitor because of the blockchain that makes every transparent transaction able to create a new system that is more trusted.
They don't need to like bitcoin but they benefit the blockchain, there are banks who are using stable coin for their business and they also want to promote transparency, so it's an evidence that bitcoin is very helpful for their business as without bitcoin there will be no blockchain.
Bitcoin now is now is more important as an investment because there are a lot of coins better than bitcoin as a payment system.
Indeed bitcoin can help in many ways not just businesses, but also for those people who wanted to change their traditional way of payment. Cashless way of using money as a mode of transaction is the best benefit that we can acquire once bitcoin will become a leading currency. But for now it cannot be appreciated yet with other non users, because it wasn't introduced publicly and yet some other people didn't view it as legit way of using money digitally.
