Banking system is on the verge of collapse. They are threatened by the growing cryptocurrency market and can't afford to have people shift away from their ridiculous system.
They have employed bot trading into the cryptocurrency market. Check the last 7 days trading graph for BTC and ETH, they are like identical twins!!! Each dip and rise corresponds literally on dot.
The banks are trying to scare away people from the cryptocurrency market as they stand to lose a lot from their immediately collapsing model (max 3-6 months). They don't want people to shift from their market to the crypto market.
Perfect time to hold on to what you have and buy more when the market dips. Let them invest to mess the market, we will be smart enough to take their money when they lose at both ends ;P
