A lot of them have no idea how to lift a weight from the floor either. And they probably are doing squats in the Smith Machine and leg presses instead of Olympic Lifts.
The best way to approach real lifters is explaining like this:
Fiat money is like isolated exercises (peck-deck, biceps curls, leg extensions, etc.). The external machine 'assist' you in the movement. It doesn't work. If you wanna grow, avoid this trap.
Bitcoin is like sprint training and compound exercises (squats, deadlifts, snatches, clean'n'jerk, chin-ups, push-ups etc.) You don't need an external machine to 'assist' you in the movements. With Bitcoin, you are your own gym.
