"Most people who made and kept large amounts of money in cryptocurrency simply survived and held on long enough to get a few big wins.
You don't need much for this.
To survive and be around for these opportunities, your priorities are:
1. Reduce existential risk (cross-margin trading without a stop, all in one coin or position, all funds on one exchange, all funds in one hot wallet, and so on).
2. Minimize the size of your biggest losing trades. Your trading history should consist of small losses, break-evens, small wins, big wins — and never big losses.
2.1. This is a more nuanced approach, but in general, it means you shouldn’t add to losing trades without a plan, shouldn’t exceed the maximum position size or risk per trade, avoid excessive leverage, avoid overtrading (many small losses quickly turn into large ones), have clear criteria for entry and exit (for both winners and losers), and other basic principles.
There’s no mystery here — 99% of the time, you know when you're trading like an idiot."
