On the day when the account with 3 million was lying there, I dug out the bank statement from 2016 - the balance was 50,000, and the company had just gone bankrupt.

That week I spent every day on the trading platform watching the candlestick charts, and in the end, I gritted my teeth and went all in on 8 $BTC, with a cost price of 6000 each. Looking back now, there really was no turning back.

In 2017, the market exploded, and Bitcoin increased more than tenfold throughout the year. I watched my account grow from 50,000 to 800,000, so excited that I couldn't sleep for nights. At that time, I really thought I was going to get rich, until the market halved in 2018, and my account was cut down to 180,000. I sat in front of my computer in a daze for a long time before realizing: the numbers on the screen are not really your money.

Since 2020, I stopped playing the game of chasing highs and cutting losses, and instead focused on mining and DeFi. After three years of effort, my account has stabilized at 3 million. Many people ask what hundredfold coins I've caught; to be honest, surviving in the crypto space for a long time is the real skill.

Over the years, I've gained a few experiences, and today I will share them all:

**Protecting your principal is more important than anything else.** During the altcoin surge in 2021, I bought a coin that rose by 50% and then withdrew my principal. Later, it dropped by 90%, but I still made a profit. There are plenty of opportunities in this market, but if you lose your principal, you're completely done.

**Don't touch things you don't understand.** White papers, team backgrounds, token models—if I can't figure one out, I won't touch it. I didn't participate in the IEO boom in 2019; it all collapsed afterward. Before Layer 2 took off in 2021, I spent half a year researching the elastic sidechain technology of SKALE and got heavily invested in advance, reaping several times in returns.

**Position allocation is much more reliable than bottom fishing and top escaping.** I have always used the "6211 Rule": $BTC and $ETH account for 60% as the base (these two together account for more than half of the market), mainstream public chains 20%, new tracks testing 10%, and leave 10% in cash. No single coin should exceed 15% of the position, and in a bear market, the maximum drawdown is 12%.

Bitcoin has dropped from over 120,000 to over 90,000 now, and altcoins have been cut in half, further proving that the rules are effective. Don't get too carried away in a bull market; stock up more in a bear market. The ones who really make money have never been gamblers, but those who understand the patterns and can control the rhythm.

Market conditions change daily; by protecting your capital and maintaining the right mindset, you too can turn things around in the next cycle.
