I agree some of this is "healthy" and the churn is good, shows liquidity for those that are looking to put some in. All the things that are going on right now are finally the signs of a healthy trading stock.
I will say though, that when someone destroys the bid down to .0022 when they could have sold yesterday for .0026-.0027 that they are deliberately trying to manipulate the stock down. I have very little patience for that, but I do have a very strong resolve, so it will never work on me.
