Why do these people do this? Are they just morons?
If they would sell their coins within a period of 3-4 days they could probably get close to 8000 USD for every single BTC ...
Some took the opportunity to cash in the gains from the last days.
I believe that there's a possibility that somebody thought he'll be able to lower the price a lot more and profit, but failed to do that (the market didn't follow the downtrend and stabilized at 7000-7200).
