I would also like to add something I said in the contest thread:
"One of the best things to do is to not watch at all. This is just my opinion, but if I really wanted to LEARN a trick, I would never look for a tutorial on YouTube. There is no substance to their teaching, because they aren't teaching you anything. They just show you how it's done, rather than give you tips to make sure you are performing it correctly. That is why it is important to learn from the original creator, because not only do you learn the trick properly, you get really insightful tips and handlings that no one else but the creator can give you. The majority of the big magic channels on YouTube are fake magicians; their purpose is to get paid for views. Plain and simple. They don't care about the audience, or want to engage with them, they just want your view."
So like I said above, these people get paid for exposing magic they didn't create, which is 100% unethical and wrong. Anyone who "learns" from these guys are only doing themselves a disservice because they will never understand how the effect works, what they're doing wrong, and they just copycat. If you really want to be a magician, learning from YouTube will get you nowhere. Like ChristopherT and Randy said, do your own thing and perform your effects with your own unique personality. You'll set yourself apart from everyone else doing the same effect.
