Signal groups almost never work, and I've joined quite a few in the three years that I have been trading cryptocurrency. It's definitely not worth the money in the end, because some groups may turn out to simply be altcoin pumping groups in the end, or the signal accuracies are just not as good as claimed. Either way, learning to trade takes time, and joining a signal service isn't much of a shortcut. I highly suggest you take the time to learn how to trade yourself. It does take time, yes, but you'll be able to trade as well or better than whoever you linked in your video.
