Does they are willing to sell the tricks? Or they have linked any website url in videos descriptions? I am asking this because they might share some ponzi scheme site or some ponzi wallet which allow to use stake their bitcoin (means Holding bitcoin on their wallet) and they will share some interest. That means it's a way like ponzi.

But I did not hear something like that where I can take profit without selling BTC. And I am not sure though if there any way or not. My guess they are talking false and trying to scam people when they will follow their step or when people will be interested to buy the tricks.
