Selling stocks and get into the bitcoin can be good but be sure that you do it with a low price.
The bitcoin is a good investment but keep in mind there can happen a lot.
i agree better to try bitcoin trading first before selling all your stocks unless you are in a profit in your stocks, i would recommend to sell portion of it and then buy bitcoin with the sold portion. Now you have to stocks

and have two ways of earning, previous stocks and your bitcoin stocks.
