Doesn't it depend on what you mean "you understand bitcoin"? I mean, you can understand how you need to use a light switch, without understanding the underlying working mechanism. Couldn't that be the case with btc? 🤔
Yeh, but I’m an electronics engineer, I do understand the underlying mechanisms down to the quantum uncertainty layer, of which I am certain 😂
Also, I’ve decided I definitely don’t understand Bitcoin, despite studying it for nearly 4 years full time 😂
Not really bitcoin related but a good read thou https://cdn.mises.org/Human%20Action_3.pdf
