If you want to make money in the crypto world, you first need to understand how virtual currencies work. I recently整理ed and found that most people actually lack understanding of the pros and cons of various trading methods, blindly following trends ultimately turning into cannon fodder.

The simplest is buying low and selling high, similar to spot trading in stocks. The coins you buy belong to you, regardless of how the price moves, the amount in your hands remains unchanged. The downside is you can only profit if the coin price rises; when it falls, you can only cut losses or simply hold the coins passively. If you want to play short-term swings, the risk increases significantly, unless you have a very large capital.

Then there are futures contracts, which appeared only after 2018 and are popular among traders. You only need a small margin to open leverage, supporting both long and short positions. High returns with small capital to make big gains sound very attractive, but the risks are also extremely high, potentially leading to liquidation and losing all your principal. It requires very strong psychological resilience and is generally not suitable for long-term investing.

Airdrops are free, divided into active and passive types. Active airdrops require you to complete tasks for the project team to receive tokens; passive ones are rewards just for holding certain tokens. The advantage is no additional investment needed; the downside is active ones are time-consuming, passive ones have low success rates, and the tokens from airdrops are often worthless.

Mining with mining machines yields relatively stable output,属于 passive income, so you don’t need to watch it every day. But the payback period is very long, the initial investment is high, and there are serious legal risks and issues of capital monopoly.

Arbitrage trading exploits the price differences of the same coin across different exchanges. Buy where it's cheap, then immediately transfer and sell where it's expensive. It seems simple, but if the price difference isn’t large enough, it can’t cover transaction fees and withdrawal costs, leading to losses. Plus, you need to be quick; if you're slow, the price gap will be arbitraged away.

Holding coins to earn interest is like bank deposits: deposit coins into a platform to earn interest, divided into flexible and fixed-term. It's simple to operate with no threshold, but the returns are very low, and the interest often can't offset the risk of coin price decline.

Regarding actual profitable methods, I’ve looked into the main modes. For complete beginners, rather than trading coins, it’s better to hold Bitcoin; long-term bullish dollar-cost averaging has the highest success rate, but it takes a lot of time, so few people do it. Futures trading with high leverage is more like gambling; technical analysis is basically ineffective, and success rate is lower than getting into Tsinghua or Peking University. On-chain trading and primary markets with hundredfold leverage can make you skyrocket if you catch the right opportunity, but it relies on information and experience, with success rates of only a few in ten thousand. The most reliable is still spot trading with a long-term trend strategy; about 20% of people succeed, key points include good operational strategies, such as trend prediction, coin analysis, position sizing, batch operations, and timing entries and exits at bottoms and tops.

So, how to play with virtual currencies? The core is to find a method that suits you, rather than blindly following trends. Every approach has risks; the key is to understand your own risk tolerance and time investment.
