Sold 20% of my stash @ 100 Billion marketcap. Looking back I should have sold more though. 
This deep correction was to be expected with so much hype going around.
We had a very (unhealthy) parabolic bull run upwards in the last few months.

Got in the cryptomarket @ 20 Billion marketcap, so I am not too worried (yet).
Most of my holdings are for long term investment.
