Recently, I've been thinking about how many ways there are to make money in the cryptocurrency field. To be honest, many people might think it's just buying and selling coins, but it's actually much more than that. I think it's necessary to summarize because there are indeed quite a few methods that can help you increase your returns, and the key is to find the one that suits you best.

Let's start with the easiest method. Airdrops, simply put, are tokens given by project teams. Some require nothing from you; as long as you hold a certain coin, you can get free tokens, like Bitcoin holders who received BCH airdrops back in the day. Others require active participation, such as registering an account or performing on-chain interactions to earn rewards. I think this is a good starting point for beginners, especially if you have plenty of time but limited funds. Of course, the drawbacks are obvious—sometimes it’s very time-consuming, and the success rate isn’t guaranteed; the tokens you get at the end might not be worth much.

Next is X to Earn, including ways like playing games to earn coins or exercising to earn coins. Projects like Axie Infinity and STEPN are representatives. The benefit of these is combining entertainment with earning potential, which seems quite fun. But frankly, you usually need to invest money upfront to buy equipment, and as more people play, rewards decrease, and the coin prices might also depreciate.

SocialFi is another approach—earning coins through social activities. You can post content on Mirror or Twitter to receive tips, or share and interact on other platforms to earn platform tokens. This method has a low barrier to entry and doesn’t require investment, but the problem is that token prices are often not very attractive, and if you lack fame, tips can be hard to come by.

I’ve also paid attention to NFTs. You can turn your creative works into NFTs and sell them on OpenSea or Rarible. For example, an Indonesian guy turned his selfies into NFTs, with a trading volume reaching 400 ETH. That’s quite inspiring. But the reality is, most people’s NFTs might not sell, and it requires some professional knowledge.

If you want relatively stable income, mining is an option. Using specialized mining machines to mine Bitcoin, Litecoin, and other coins, with relatively stable output, is considered passive income. But honestly, the payback period is long, the initial investment is high, and you need to find places with cheap electricity—which can be difficult for ordinary people.

DeFi mining is another idea. You can contribute to decentralized finance, such as providing liquidity on DEXs like Uniswap or lending on platforms like Compound, to earn rewards. This method often offers generous rewards, but it requires a good deal of expertise and carries liquidation risks, so it must be approached cautiously.

There’s also a simple way called holding coins to earn interest. Just deposit your coins into a financial product on a major exchange to earn interest. It’s straightforward and relatively low risk, but the returns aren’t high, and sometimes the interest earned might not offset the loss from a falling coin price.

Spot trading is the most classic method—buy low, sell high. It has the lowest threshold and is the simplest to operate. If you hold coins for the medium to long term, the risks are more manageable. Short-term trading might sound exciting, but it increases risks significantly. Unless you have a large amount of capital, it’s easy to suffer losses.

Futures contracts are, honestly, a high-risk game. You can open leveraged trades with a small margin, taking long or short positions, but the risk of liquidation is very real. This method isn’t suitable for those with weak psychological resilience or for long-term investing.

Finally, arbitrage—moving coins between exchanges. If the price difference is large enough, you can buy on the cheaper exchange and immediately sell on the more expensive one. This method has relatively low risk and stable returns, but opportunities are rare, and you need to be quick—if you’re slow, the price gap might disappear.

Currently, Bitcoin is at 77.56K, Ethereum at 2.14K, and Dogecoin at 0.10. Honestly, choosing which method to make money ultimately depends on your own capital, time, energy, and risk tolerance. Not all methods suit everyone, but there’s always one that can help you improve your returns. The key is to find the one that fits you and stick with it.
