I don’t think banks are the ones against Bitcoin. It should be the government that is against Bitcoin because they don’t have control over it. The banks actually report to the government and because Bitcoin isn’t doing the same, they don’t like it. Because starting from tax and other things they’d have implemented or rule they’d have set, they can’t. Bitcoin takes out the middle man and the government can’t do nothing about it, no matter much they dislike it.
Both banks and governments are against bitcoin,the bank is government,the government works with the bank as well.Therefore,prohibiting bitcoin from operating freely is highly a setback to bitcoin.The government would always want to promote whatever they're In charge of,so if it doesn't work to thier expectations and how they should operate then it becomes a problem to them.
Bitcoin is not backed by government,bitcoin only operates as a peer 2 peer network system,thereby fixing the issues that fait seems difficult to handle.
The transformation that bitcoins adoption has created has laid traces and lasting changes in financial technology.
