One can state that trading activity is really easy and I can't not to agree with this point. It becomes easy as soon as you gain some knowledge and experience in this field. Until you don't start trading it seems to very difficult and you think that it's almost impossible to make money here, however it's not like that. I always advice such people who always doubt that they need to try and only then they can make conclusions towards trading. Moreover, if you will lose your money on your initial stage, then it's okay, never give up and everything will be okay. I am tend to suppose like that actually.
This growth was in trading always actually. If we look at the graphics of all tech companies in the world, not only tech actually, we can see that all of them show stable growth on the 10 years graphic. Thus, it can't sharply drop down in my opinion. Everything is growing because economics are growing too. Hence, the best way to earn money on this growth is just to join trading activity I think. Never doubt that something might go wrong. If you consider investing, for example, then nowadays is a good opportunity to start investing, because companies grow pretty fast, up to 20-40% per year. The vast majority of companies want to grow, hence their stocks grow too.
Trading is easy only in case of proper learning and practicing. There are no easy activities in our world, all of them require some experience and skills. Actually, if you will think that it's easy it can be pretty useful for your results in trading. Anyway, traders should seriously approach to trading activity and it doesn't matter what direction does the price take nowadays. Even if there is a strong bullish trend on particular asset, it doesn't mean that you should open only bull positions. You should calculate and analyze everything before opening a position. So, only if you will learn and practice properly, you can gain results.
