Interesting and informative article. I feel that once banks realise that they are in serious danger of becoming dinosaurs in the financial world, they will move heaven and earth to retain their stranglehold on the global markets, and continue to fulfil their legacy of keeping the rich, rich and the poor down at heel. Unfortunately, for them at least, I dont think that future blockchain developments will allow them to do so. The writing is, IMHO, definitely on the wall.
