If youre busy the best way is to research and find undervalued and solid coins and HOLD it. this will have less risk and less stress monitoring always your portfolio. i think that is the best way as many people have different available time in crypto
THIS. I used to day trade a bit using online stock accounts (Robin Hood, Scottrade, etc). I eventually found that, if you're not playing with extremely risky stocks (or in this case coins), you're better off picking things you want to hold long term. You CAN get a greater reward day trading, but you have to weigh it against the amount of time and work involved, and honestly keeping up with my miners and general coin rates is exhausting enough, I wouldn't want to add day trading to my workload (I have a job and a gf and everything as well, time is a valuable commodity these days)...
