Due to missive rise in cryptocurrency market in last 1-2 years, we have seen that the HOLD is the best strategy to follow. Trading is risky and requires some experience in past.
both are great and better to do, but i would love to choose to hold, yes its not easy both to do in trading there is a possibility i think that you will loose or even your profit goes down, so i must prefer to hold that trade we dont know what will happen though,
both can be done when you have a lot of money, and are ready to take risks. both options can make you earn so much money in the future. it's just that, the risk that you receive will feel bigger. for now, I just hold a few coins for the future.
