Day Trading: Make a short profit and secure your finances every day.
Hold: make big profits but take a long time.
Depending on your choice, if the amount of investment you do not need is used, holding would be a better option.
For me Holding coins for a long time is not for me also some coins is already dumping it's price now and maybe your coin will get affected later.
I also try hold for long time and nothing happends until this year of 2018 When i see my funds lossing every day.
At first I thought holding coins can give us a lot of profit but I think this is not true this year. Prices of almost all the coins are same or even less and it is not worth holding.
