When an asset (such as bitcoin) is oversold, any positive news (even only a slightly positive one) will make he asset price move up. This is because in an oversold situation, the asset price is getting ready to snap back towards mean reversion.
I am happy that bitcoin is finally moving up. I am a little upset, though, that I couldn't hold on to all of my coins. I sold 5% of then near the bottom :( Looks like I will have to repurchase them soon.
