I've been hustling in this field for seven years. Started with a principal of 50,000, and now my account is at 7 million. I've been through three bull and bear cycles, and to be honest, surviving all this relied entirely on a few rules I figured out for myself.

Once, I overheard an old hand in the industry say after a few drinks that he lost 50 million in just three days by over-leveraging contracts. That made me realize that the biggest dangers in this market are greed and impatience.

I only follow one principle when picking coins: does it have real fundamentals, and does it have enough recognition from people? As for entry timing, I always choose the tail end of a bear market, when the market is as cold as an ice cellar and most people have already left. But if you wait patiently for the bull market to come, doubling your money is the norm.

I use two indicators for exiting at the top: if Bitcoin’s market dominance drops below 40%, it means capital is pulling out; if the ETH/BTC ratio breaks 0.1, it usually signals a correction.

Bitcoin is my ballast. I use grid trading for swing trades: when prices rise, I switch to Bitcoin; when they fall, I add to my positions and buy the dip. My long-term positions remain untouched, while I do short-term quantitative arbitrage. This combo has brought pretty decent returns.

The most critical thing is endurance. Accumulate slowly at low prices, do your research on projects, and don’t chase the highs. If you get through the troughs, the bull market dividends will naturally come to you.

There are indeed plenty of opportunities in this market, but if you’re headed in the wrong direction, no amount of effort will matter.
