I believe a big mover for banks is automation and new forms of cryptocurrency. Bitcoins with block chain and how decentralized that can be is a game changer. China recently outlawed then decided to embrace cryptocurrency with restrictions of course ;-). Changed the market overnight. https://www.cryptocoinsnews.com/china-will-likely-resume-cryptocurrency-trading-by-licensing-bitcoin-exchanges/
A very small example indeed but as big governments try to spend less on making currency, it costs about 1.5 cents to make a penny. https://www.cbsnews.com/news/it-cost-1-5-cents-to-make-a-penny-last-year/ that’s not cost effective at all! Cryptocurrency will have a new cost model that could be far more financially positive for some.
Government moves into cryptocurrency will be for tracking and fraud prevention. And, for detecting money laundering operations. Maybe cryptocurrency will devalue gold and silver. Who knows?
But, the biggest thing out of all the move to cryptocurrency will be massive layoffs in financial sectors of all industries.
That is a game changer.
