I had a look in that site, there is no performance showing if the signals are actually good and working like they should so I would stay away from it. If you are going to use bitcoin signals then make sure there is a very clear performance.
I did come across ddmarkets, they been giving forex signals (not bitcoin) for a few years and looks like they started giving outlooks and signals for bitcoin, ethereum and ripple coin. It's still very new but you can actually see how the signals and forecasts work.
I sallute you for this. You really exert an effort in sharing this with us. This will serves as a guidelines especially for newbies, like me. Thank you for this.
