Why not try the two options and see it for yourself. Just start small and assess yourself what do you prefer. Take note that it doesn't a;ways mean the longer the time frame the higher the profit. It always depends on many factors. You can't always says that you can gain in day trading as it can be very risky specially for beginners. Hone your skills first and familiarize yourself with how the market moves. Day trading, mid term, or long term has its own advantages and disadvantages, it depends on you how to deal with it. And on a side note, 100% to 800% is so high. Try to lower it down. Always manage your expectations.
