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.
Thinking the same thing if its not needed you should not do it because it than would be stupid to do honestly.
It would simply not be smart at all.
