MONK - The ultimate POS, or the pump-y?

I bought in on MONK during it's ICO (0.89 cents per). Ever since than it has NEVER been in the negative (In relation to 89 cents). And it's been, hyperactive over christmas. SHould I sell all? Or what to do... Hmmm...
Example of what I mean: MONK/USD

How much did you invest?
