I agree with all you wrote @edith4angelseu with the exception of time. I do not think the banksters are going away soon. They still have a number of years left in them. This will not happen overnight.
Blockchain is still in its infancy...we will see a lot of growth over the next 10 years.
I know it will take time but it is already in the making, little by little, more people are flowing into blockchain because the veil is being lifted. But like you said, it's a matter of time.
