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.
Mostly coins are of pump and dump nature and other moves on the news. After the pump and or then event completion the prices go down again, so I think its better to do day trading and book profit with up and down of coins.
