Day trading is time intensive because you need to fully master and put to use every methods ranging from fundamental analysis to technical analysis. I prefer long term hold because it gives me time to engage in other activities and it is more profitable. Day trading is only profitable when using a huge amount of money to trade.
Both methods can give you competitive returns or profits depending how much you invest to hold and how much you put to eventually trade. Also it depends if you are somehow an experienced trader or not, because if not, then holding bitcoins is your only best option. Just make sure that you have plans when to sell it so that you can make profits, it doesn't matter how much you invest, the bigger you put, the bigger the profits. And you can also buy at a fraction and buy again sometime later, it's just a matter of patience and timing.
But if you really want to trade, you can always learn it because it's not probably too late for you to learn. There's so many available methods and beginners guide in the internet if ever you want. Just put some extra effort to it.
