I already answered that question extensively. But if you don't read my postings you will keep repeating this question.
For me trading is indeed easy now (for many years it was not). I am not interested in trading more often and I am not interested in billions. Read all my postings and you will know why.
Quality of life prevails over quantity of money. But to understand that you should first make enough money to have the luxury that you can refuse extra money and receive in return quality of life.
Only newbies who haven't been around for very long say it's "easy". In 2007 everyone was running some sort of a dip-buyer and thought it was easy, then came 2008.
He sounds just like those people (I used to be one of them), there will be a time when the whole tech sector drops -20% quickly and there won't be any bounce.
I'm curious if you and your friend actually trade for a living, if not then it doesn't matter because it's more a form of gambling than a serious career.
Problem with your statement is that you could make more trading the "easy" way for a few years, then have the highest quality of life possible.
Why would your quality of life suffer since you said it's the easier way to trade?
My guess is you really haven't figured out how to actually trade very short term but you think it might be easier.
In fact I find short term movements more abrupt since all it takes is one player in the market who needs to unload his shares fast and that will pull down the market. If he unloaded the same amount over a longer time, he would impact the market much less.
