Day Trading might be stressful but the you could have a gigantic profits here compare if you are going to long trade. Long trade form me is like holding, doesn't have any analysis at all so it is easy but your profits is not that big, it is only could for amateur Traders and staying on the safe zone. There are disadvantages and advantages for both of them, the most life consuming is Day Trading, too much radiation, can't get enough sleep, insomnia, low blood pressure and so on.
I would choose long trading also, because what would I do with a lot of bitcoins if I'm going to become a sick person, and there is a saying that "health is wealth", I'm sticking to it.
