Around 2016, I first came into contact with Bitcoin (BTC), but at that time I was not familiar with how to participate and could not truly enter this field. It wasn't until 2017 that I officially entered the crypto space. At first, I mined Ethereum (ETH) at home, earning a few hundred yuan a day. Based on the market conditions at that time, I could recoup investment in about four to five months. However, I ultimately didn’t make much money, mainly due to the fall in coin prices, coupled with significant losses when selling mining machines. By June 2019, I accidentally got the opportunity to buy mining machines to mine BTC. However, due to many issues with the mining farm, this experience still did not bring considerable returns. I started trying to trade with the mined coins. Initially, I made a little money using 10x leverage, which made me a bit complacent, thinking I had mastered the "wealth code" of the crypto space. However, reality soon dealt me a heavy blow. I remember the day of the "312" big dump; before going to dinner at 6 PM, the coin price was relatively stable, but shortly after I arrived at the dining location, the coin price plummeted like a waterfall. At that time, I even bought USDT to average down at over 10 yuan, but ultimately, I was still liquidated, losing more than 4 BTC. At that moment, I truly felt a sense of "giving up on life." Despite this, I did not completely give up and reinvested 250,000 yuan to continue trading, but the results were still unsatisfactory, with heavy losses. Looking back on these experiences, I realized that the root of the problem lay in my eagerness to make quick and big money. After some painful reflection, I began to adjust my strategy: I was long-term bullish on BTC but had to operate more conservatively, no longer using high leverage, and worked hard to slowly recover my losses. After the BTC halving in 2020, the coin price rose from over 3,000 USD all the way up. I resisted the urge to act too early and only started to gradually reduce my position when the price reached around 30,000 USD. Before May 2022, I had successfully withdrawn 1.35 million yuan, and the account's market capitalization grew from 220,000 to 480,000 at its peak. At that time, I thought the market would continue to rise, but the market reversed at the most unexpected moment, causing my assets to shrink significantly. To "buy the dip," I averaged down three more times, investing a total of 150,000 yuan, but the market capitalization once fell to only 170,000 yuan, leaving me very anxious. Even so, I firmly believed this was just a temporary decline and remained bullish on BTC's future. At the same time, I also formulated a clearer operating plan for myself: starting from a coin price of 30,000 USD, for every increase of 5,000 USD, I would withdraw 50,000 yuan. Fortunately, I kept at it, and both the market capitalization and withdrawal amounts continued to set historical highs. So far, I have withdrawn a total of 2.05 million, with nearly 500,000 remaining. Summarizing the experience of these years, I found that to truly earn money and big money in the crypto space, there is only one method: accumulate coins, accumulate coins, and accumulate coins.
