Would have been really useful at the beginning of January when Bitcoin started to boom. To be honest that was the starting point from which I decided to start with investing. I've own a few stocks here and there, i'm not completly new to CFDs and Forex, but I've never paid a lot of attention to the market, or to be more accurate, I've never paid as much attention as I would have needed to actually get somewhere with this. So, I'm still a beginner if you haven't figured that out, haha and apps like these are really useful, or at least they are in my situation. Another one that I've been getting a lot of great use out of is Investous, maybe you want to give that a look as well.
