In November 2019 price of EDC temporary for 1 day raised to 0.015 and then it falled back to 0.006. It was somethink like market manipulations.
I remember how this case of temporary raise was discussed here on the forum. But after that the price of EDC returned to 0.006
This may be due to the fact that for example there is some kind of major player, there has been a growth and he began to fix the profit, thereby returning the price back.
