Personally I prefer long-term investments. Because daily trading requires more time resources and it is too risky. Long term investments if you choose right asset, it can guarantee you with income.
I also think the same with you, daily trading also takes a lot of time to monitor the market in order to get the maximum profit
Apart for time resources which I think can be handle on the go through the use of mobile phones, no day trader will earn $50 per day now or else if the trader have the money to buy 1 or 2btc.
