Maybe in some new episodes that I didn't watch yet.
They recently had an episode specifically about BTC. One of them had lost crypto that they mined a long time ago, or something along those lines.
I was reading that only 2% of people know and use it
It's impossible to measure how many people use it unless you manage to compromise the pseudonymity of every single BTC user in existence.
As for how many people know about it, that statistic is incorrect.
Still, the general point that the price shouldn't affect BTC's perceived adoption is pretty sound. Merchant adoption has stagnated while people use BTC hugely for speculative purposes.
