Seven years of ups and downs in the crypto space, turning 50,000 principal into 7 million, and surviving three bull and bear cycles—looking back now, I owe my survival to a few iron rules.

First, a lesson learned: I once saw a big player drunkenly confess to losing 50 million in just three days of leveraged trading. That night, I realized that surviving longer is more important than making quick profits.

My strategy is simple—I only pick coins that have real-world applications and community consensus. I avoid pure hype and speculative junk completely. Timing is even more critical: I only enter at the tail end of bear markets, when market sentiment is at its lowest, and then wait for the bull market to reap the rewards.

I always watch for two signals to exit near the top: when Bitcoin market dominance falls below 40%, it means capital is starting to flee; when the ETH/BTC ratio breaks above 0.1, it often signals a coming pullback.

Bitcoin is my anchor. When prices rise, I swap alts for BTC; when they drop, I use BTC to buy the dip. I use grid trading to swing trade. I hold coins long-term without moving them, and use short-term quant strategies to capture price differences—this combination has yielded decent returns.

In the end, patience is the rarest asset. Lay low at the bottom, dig deep into projects, don’t chase pumps, and don’t act rashly—if you survive the winter, the bull market rewards will naturally come to you. When you’re headed in the right direction, only then does hard work have real meaning.
