I think it's more a function of price extremes? While low liquidity can exacerbate volatility, the primary drivers are still shifts in market sentiment and release of new info etc
I agree with you btw, I don't think it's enough to work hard and never said that
The frustrating paradox of trading is that "hard work" aka consistent effort which would usually lead to a promotion in a conventional career or at the very least pay the bills, is only the starting point here, with zero guarantee of profit
Only deepwork really shifts the odds, otherwise all of my friends would be top traders by now
