It's depending a lot on supply and demand. The more people are buying the higher the price will go up.
I'm pretty certain bitcoin will reach above and beyond $400
Buying is not always good Guess you never brought at $800 and above? You are right though it does indeed help the market. The supply and demand, when there are more buyers than sellers is when we see the rise. I am hopeful we will see a nice amount over $400 this year.
For now thoughm I have stopped buying until there are a few bits sorted out that are currently not and besides I have brought for the last couple of years and have enough.
