If you are referring another correction as manipulation then I guess we may have that anytime as bitcoin market is facing strong resistances around $55k to $57k levels which may persist for few more days and in between time, we can see bitcoin prices may slide down up to $51k levels. But, these are all usual correction period of bitcoins and I am not ready to term these as manipulations.

At the same time, I have seen many times whales were trying to catch cheaper prices by inducing panic among traders but now a days whales are slowly losing their power against high volumes of most exchanges.
