while surfing the net, i get some pop-ups directing me to the article of persons who claim to have made really big and quick by just predicting the rise and fall of some binary digits (They call it trading). This is the link to the website for predictions - https://olymptrade.com/platform. If you are into it, my question for you is "does it really pay?" also tell me what you think of it.

You must be a master trader when trading big and quick. This is been done by many and they also succeeded because they are well prepared when doing this. So, yes this is effective way also and many are doing this, but in quick trading you must be watchful every seconds od the marker movement so that when it hit high you are wide awake when it happens, and do a quick selling if you want to.
