Recently, someone asked me how to operate arbitrage through "moving bricks," so I decided to organize my understanding.

"Moving bricks," in simple terms, means buying low and selling high. You purchase a certain cryptocurrency on a platform where the price is low, then transfer it to another platform where the price is higher and sell it. The difference minus transaction fees and withdrawal fees is your profit. It sounds straightforward, but in practice, there are many nuances.

Let me start with the most basic fiat currency arbitrage. The globally recognized trading pairs on major exchanges are Bitcoin and Ethereum, as these are the most liquid. For example, suppose you buy 1,000 EOS on one exchange, spending 12.35 ETH, then transfer those 1,000 EOS to another exchange and sell them for 12.49 ETH. Ignoring fees, this arbitrage cycle earns you 0.14 ETH.

The appeal of traditional arbitrage is its very low barrier to entry—anyone can do it. Most exchanges can be registered within five minutes, and then you can start immediately. But there are obvious issues—requiring significant time and effort to find price differences, deposit funds, buy, transfer, and sell. The entire process is quite tedious. Plus, withdrawal times can be a problem; during that period, prices might drop, causing losses. Moreover, as more people engage in arbitrage, the price gaps disappear quickly, making competition fierce.

Later, some developed automated arbitrage programs that handle this process. These programs continuously monitor prices across two exchanges, and once a price difference is detected, they simultaneously buy on the lower-priced platform and sell on the higher-priced one. What are the benefits of this approach? Very low risk, because the buy and sell are executed simultaneously, minimizing the chance of losses. Plus, the entire process is fully automated, requiring no manual intervention, saving time and effort.

However, automated arbitrage also has drawbacks—fund utilization isn't 100%. You need to reserve a certain amount of USDT or BTC on both platforms to act immediately when a price difference appears. This means your capital is split, preventing you from fully deploying funds in a single direction.

Overall, arbitrage through "moving bricks" is essentially a zero-sum game, profiting from market inefficiencies. As the market matures and more large players participate, individual arbitrage opportunities are increasingly squeezed out. If you really want to do it, automated arbitrage programs are a more rational choice, but only if you have enough capital to distribute across multiple platforms.
