Day trading seems a better choice for me. Holding is also fine but in my opinion, you bigger capital to hold than you need to trade.
Well, day trading can offer superior profits if you are a good trader but it can also offer terrible losses if you are not good at it, holding offers both earnings and losses too, but if you hold enough there is a point in which is almost impossible to get back to the original price that you bought and the best thing is that this can happen very fast, those that bought at 1000 dollars are in a good position because I do not think we are ever going to see bitcoin at that price.
