Understanding tech isn’t even really necessary with BTC anymore. Depending on age (boomers that can’t use an iPhone etc).
The understanding money part is the biggest issue. People just don’t understand or care to understand money.
Spending time on this, for me, made me a maxi.
And by that point (2017) BTC had already crossed barriers through time that made it “proven”.
People that invested in BTC very early, 2009/10/11 are real warriors and understand the tech 10000% better than most.
