It's on a decline?
It is. On a huge one. Look at those sell order volumes. Someone is cashing out their ICO investments.
This only means that it's a pretty good price to buy some more for future.

Hmm will it go back up in the next few hours though?
Yes, in a matter of hours ..
Dont get FOMO over this
Good Advice!
In case price spikes on there, move some of your MCO to Binance. Up to 3 BTC. As this is the withdraw limit for unverified accounts.
