look at this sexy healthy graph.. crash can be VERY profitable long term if you have impulse control and keep yourself from tilting or fomo'ing.
take small wins (multiplier) and be happy with them, 1.4-2.2x, build a buffer then go for 3-20x, then go back to conservative wins to rebuiild buffer.
graph above is second half of a 4 hour grind of a 200 -> 2k session. betting 5$ per round, eventually upping it to 10 then 25$ a round as bankroll grows. very repeatable.
