I've noticed that many beginners in trading eventually encounter one strategy — and it either saves them or ruins them. I'm talking about Martingale.

Martingale is essentially a simple idea: if a trade goes against you, you increase the next one. Lost — double the stake. Still unlucky — increase again. The logic is clear: when the price finally reverses, your large position will cover all previous losses and generate a profit.

This idea comes from casinos, where players have been trying to beat roulette for centuries. Bet a dollar on black, lose. Bet two, lose again. Four, eight... And then the eight wins. All losses are covered, plus a small profit. Trading works similarly, but instead of colors on roulette — real asset prices.

In practice, it looks like this: buy Bitcoin at $50,000 with $100. The price drops to $49,000. You open a new order for $120. It drops further — now you buy at $144. The average entry price gradually decreases. When the price bounces up even slightly, you’re already in profit on all positions at once.

It sounds like magic, but there’s a catch. Martingale is a high-risk strategy because your deposit can run out before the price turns around. Imagine: you have $1,000. Started with $50, then $60, then $72, then $86, then $103, then $124... and now you’ve spent $495 over five orders, while the market keeps falling. You might not have enough money for the next order, and you’re sitting with losses.

How to calculate how much money you’ll need? There’s a formula. If Martingale is 20 percent, starting order $10, then: first order $10, second $12, third $14.4, fourth $17.28, fifth $20.74. Total $74.42. At 10 percent, it’s about $61 for five orders. At 50 percent — already $131. See the difference?

Why do many traders still use it? Because, when applied correctly, it works. But the key word is — correctly. Beginners are advised: limit your increase to no more than 10–20 percent, calculate in advance how many orders your balance can cover, avoid entering a strong downtrend (if the market is falling without rebounds, averaging is suicide), and always keep a reserve of funds.

Martingale is not a strategy for relaxed trading. It’s a tool that requires a cool head, calculations, and strict discipline. If you’re ready to assess risks and not panic — it might work. If not — better not to touch it. Trade consciously.
