I think those "experts" surely do things that are abysmal to professional trading but the reason they might not show it is because for you not to learn the wrong way and think it is the proper way. Again, some of the experts conduct seminars and tutorials for the public so you can't be seeing all losses and still have the interest to go on with them. For marketing to be successful, you have to give your best.
This is their own strategy, and we know the truth, then we should not just trust everything that we are seeing via online, there are things that they shouldn't tell to everyone and for me they don't owe everything to us, so it is fine for me, I don't care at all, I have nothing against it, what matters to me is that they are doing something that will help new traders and they are sharing their real insights about crypto world.
