Stocks are good for investing but I think that its a bit old to make profit on that way, I think the new way is doing it with the bitcoin, its pretty new for the most people and also more profitable on short terms.
I really think that its worth the gamble to do this.
I do not think that it would be a bad idea to sell your stock but I would only do it if it is not going good with your stock then just come over to bitcoin.
If you stock is doing decent then just make use of both bitcoin and stock.
