You are absolutely right. Banks has power into our society and even with the help of cryptocurrency I dont think that banks will be eliminated because even as of these very moment banks doing anything in their power in order for them to integrate into blockchain technology or adapt the cryptocurrency. Maybe as a middleman or as safe keeper of our funds maybe on that matter they will be eliminated because of the change that crypto will bring when the whole world will adapt it. If all banks accept the change that crypto will bring I think there is no danger for them just like people is telling about.
