Two weeks later re buy..?
If you are doing good with your stocks then I would see no reason on why you should come over to Bitcoin, I think that you should sell some and make use of both stocks and Bitcoin.
Then you might have more ways of income which is always a good thing.
If your stocks are doing it good you should indeed not consider investing into the bitcoin, but if this is not the point you got nothing to lose and you could step into the bitcoin easily and make some good profit, if you have the patient.
For me, never again will I buy stock with my money maybe its because of the way the market is being managed and the directors distribute peanuts as profit after they must have taken care of themselves. Bitcoin would be where I want keep my money and make reasonable gain and cash out even in the short term rather than waiting for the market which is mostly manipulated in my opinion to decide my earnings...
