I care about bitcoin. Bitcoin futures trading, profiting, begs pump and dump. The concept of cryptocurrency is prone to taking bad hits with the dump. And the long term constancy of the downward trend since 12/17/2017 says wealth is being pumped out faster than it's being put in.
I treat my animals for parasites prophylactically. Futures trading is parasitic.

Edit: must be an effect from the noise of a neo-nazi on Vice News. No extermination implied for those who pumped in July and dumped in August. Maybe taxing futures contracts harshly would help the economy.
