Absolutely right, banks do not dissappear but will be force to evolve.
Not all people trust or want to use Bitcoins and/or crypto.
But there is side-effect of Bitcoin existence, people are getting more educated
and start realizing that fiat money are based on debt and gov. can print them in excessive way,
without asking us, we want diluted money or not.
For sure, Bitcoin/alts will have impact on various payment processors.
They simply feel cometitive push from crypto.
Recently, I got email from Skrill saying they are lowering sending money fees.
You see!
