The amount is definitely too large to avoid questions. I've been asked three times. I initially traded on BitChina, but that platform is gone now. At that time, Bitcoin was only 2500. I happened to have a lot of cash while doing e-commerce. Later, it unexpectedly rose directly to over 7000, and I withdrew funds. At that time, the controls weren’t strict, and the bank asked too. I answered the phone, they asked all sorts of questions, chatting for a long time about how many acres of land I had, how many cows, my surname, where I came from, and so on. In the end, they suddenly said: 'Sir, we have a very good financial product that you might consider...' I was stunned. After that, they weren't so polite. I've heard there are many cases of frozen accounts, so I've taken a lot of precautions. In recent years, my account has only been frozen once. I just went to the counter to unfreeze it. In summary, as long as you don’t touch USDT, there shouldn’t be much trouble. There’s a lot of dirty money involved. Funds must be kept cool. Another thing is that it's best to convert it to US dollars, and then directly transfer the dollars to a foreign currency account. This is the best option. Because it has already left the Chinese financial system, and the domestic and foreign financial systems are isolated, the dollar appreciation cycle has additional benefits. I have made large withdrawals more than ten times. Nothing happened at all. I can also spend directly overseas. Here’s a secret for everyone: foreign trade company accounts can bypass foreign exchange control bugs. So, acquiring a mature foreign trade company makes trading coins much easier. You can also do cross-border arbitrage. I’ll answer some common questions that everyone has messaged me: 1. Why acquire foreign trade instead of doing it yourself? Mainly because it's troublesome, and it's best if the foreign trade account has mature cash flow. 2. Is it okay if the foreign trade company has no performance? Just trading coins? It's still best to have some cash flow. 3. How much profit is there in cross-border arbitrage? This mainly depends on the price differences between various exchanges. 4. Will there be losses? It depends on market fluctuations; generally, there won't be losses, and you can complete an arbitrage in just a few minutes. Of course, sometimes exchanges process things slowly, and if the market fluctuates too much, there might be issues, but such situations are very rare. If you have other questions, feel free to leave a comment. If you find this helpful, please like and encourage me, thank you. I may not provide detailed answers to private messages, but when I have time, I’ll write a tutorial in my Zhihu column or WeChat public account to teach everyone the specific operation process. I’ve been very busy lately.
