The number that actually matters
Not what you buy — how much
New traders obsess over which coin. Experienced ones obsess over size. You can be right about direction and still be wiped out if the position was too big to survive the wobble on the way.
Never bet what you can't lose twice
A common rule: risk 1-2% of your account on any single trade. It sounds absurdly small. It's what lets you be wrong ten times in a row and still be playing.
All-in is a coin flip with extra steps
Stake everything and one bad trade ends the run, no matter how good you are. The player who bets 10% at a time survives to use their edge.
Check yourself
You have $10,000 and a strategy that wins 60% of the time. You go all-in every trade. What happens eventually?
- You compound to a fortune
- You go to zero — one loss ends it
- You break even over time
Show the answer
You go to zero — one loss ends it — A 60% edge is worthless if a single loss is fatal. With all-in bets, a loss is guaranteed eventually, and it takes everything.
