"20% per month" and "bet once to double"—how much difference after two years?
Assume you have 10,000. The goal is both "a dozen-fold in two years". There are two paths—I’ll show you the outcomes.
Route A: the steady kind
Monthly target: +20%, no chasing highs, no over-concentration.
Compounded over time: (1.2)²⁴ ≈ 79x → 10,000 becomes 790,000.
The difficulty isn’t the math—it’s achieving 24 straight months without a single big loss that knocks the curve back.
Route B: the brutal kind
To get the same multiple, relying on "all-in and double every time" means you must be right for about log₂(79) ≈ 6.3 times—i.e., at least 7 consecutive correct calls.
Assume the success rate per attempt is 60%—which is already quite optimistic.
Probability of 7 in a row = 0.6⁷ ≈ 2.8%.
If it’s 55% per attempt, the probability drops to 1.5%; at 50%, it’s 0.78%.
And this path has no option like "if you’re wrong once, you can keep going": one mistake and it’s over, it goes to zero.
So the difference between the two paths isn’t just speed—it’s:
A: slow, but after two years you’re likely still in the game;
B: fast, but out of 100 people fewer than 3 survive, and among those 3 some are only there because "this time was luck".
Why do most people still choose B? Because B shows results in a month, while A takes two years.
The desire for "feedback right away" always beats rational judgment—this is exactly what makes over-concentration so tempting and also so dangerous.
One more thing that hardly anyone says: A isn’t a straight line upward either. In some month you may lose 8%, 10%—that’s normal. The difference is:
When you’re over-concentrated, a -30% loss requires +43% just to break even—and often you won’t get another chance.
With a small position, the same -30% loss is recoverable with just two consecutive months of +20%, basically back to even (0.7×1.2×1.2≈1.008).
The required upside to break even is always greater than the downside you suffered—that’s the entire meaning of position sizing.
Here are three practical ways:
Change the monthly "double" goal to "don’t lose + steady growth"—measure yourself with "monthly expected value" rather than replaying your capital curve every month based on single-trade luck. Don’t stare at floating gains and losses every day.
Final line:
Time rewards compounding; leverage is punished.
You can choose to turn two years into 790,000—or choose to turn one month into 0. Both are real outcomes.$ETH $BTC #比特币ETF流出4.5亿美元 #FCA突查伦敦三处非法加密交易点
