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.
As of my research during the week, I think we should now start the day trading since the stabilizing floor of Bitcoin keeps swinging and yet we're still expecting the bull to run but yet we can't feel its true run yet. Burst to 7k is uncommon which should happen always to keep our optimism precise for at least, but heck we're always here at 6k+ staying over and over.
