I wonder if the same actor pumped and then sold - there were some large 4000 and 6000 buys and sells in there.

Of course I don't mind, it's nice to see 5% fluctuations in very short time periods - it means people keep an eye and there is good liquidity for large movers.   It also means it's worth day trading and market making.

Also, I get to keep my stash level and still average down a little although the price is way above what my average buy is.
