you also have better things you can do like trade Bitcoin on leverage or forex, stocks, commodities and indexes.
In the real world, over 80% of new leverage traders lose all their originally allocated "investment" money, most within three months.
Why should it be any different in Bitcoinland?
The idea you can just rock up and make money trading complex derivative markets is ridiculous, and I would have a small bet that the people recommending it so offhandedly have never traded anything but Magic Cards in their lives.
