No, thanks! If you think this article is a piece of gem, try to explore more and you will surely find a lot more of this kind. This is nothing but a mere attempt to lure people. "the right time to trade" is overused, so is "earn big profits" as well as the "!" at the end. You can find similar strategies everywhere, not just in medium but also in steemit, reddit, twitter, telegram, and even in popular online magazines.
I read the article as well and it was somewhat entertaining since its format was a conversation more than a set of instructions about how to trade the markets, but make no mistake unless someone gives to you very specific instructions about what to do and when in every single circumstance that can come up in the market then most of the time what you are reading is nothing more than a commercial trying to sell you something and this article was not an exception.
