This isnt something new yet price spikes like these arent really that surprising anymore.If there are significant increase of price in a short duration then expect that there would be a crash or correction in next hours.
A big green candle would really have that exchange of big red one. Manipulation? Possible and its always been like this on each time we do see the market do rise up in a fast phase in a short time.
Good thing for those people who sell off in 10k - 10.400.. When taking up position on the market, dont ever tend to put yourself in the feeling of FOMO.
