Bitcoin Futures - Have we just opened manipulation?

Hello everyone,

I wanted to make a quick post about something I noticed on the coinbase exchange.

If you notice the image below, see the spikes of over 1k increase, to me this is looking a bit odd and what we sometimes see in other markets.

Let me know what you think, Im interested to see what your opinions are or theories are in regards to this spikes and if it has anything to do with the futures options!?
