It's a pity that they don't buy upwards as they drop the price down...

Bots are always walking, BTC is either stagnant or rising, and exchanges are doing dirty tricks by dropping prices lower and lower. Scammers, nothing more can be added. They want to drive prices down to a minimum so that you sell at a loss, and then they will artificially raise the price again after some time. So there is no point in being deceived; you have to hold and wait for the situation to turn around.
