We cannot exactly say which is better between the two, but it depends on your plans and goals in trading Bitcoin. If you are satisfied with your income then just do what makes you happy and profitable. Important thing is that you are earning and learning from Bitcoin trading. In my opinion, it is better to hold for a long term because for me that is very profitable because there's no series of fees when buying Bitcoin or altcoins. Since, the price and demands are keep on rising so there's a possibility to make your investments double. Better to invest now in Bitcoin because you will never know that the price will sets its record for the highest price again and again.
