The problem is that the same banks we believe will be run over by crypto are actually investing in crypto asset's...and this means that they can manipulate this market at will should they want to push price up or tank it to the ground, so saying banks will be obsolete sounds invalid or is a BID matter as they are running the financial markets.
Instead of one going down, why not see a future of both coexisting?? It's the perfect scenario if you look at this without emotions.
That is definitely the future, banks and crypto will coexist and play different roles in the global economy.
But the problem is that some people are obsessed with bitcoin and exaggerate its power, claiming that it will replace or wipe out banks. However, in reality, that will never happen. Because Satoshi made it clear from the beginning that bitcoin was created to be an alternative, he never created it to replace or eliminate the existing financial system. He knew very well that it was impossible.
So you are right, the ideal scenario is for both to coexist.
