I've made 100 million in cryptocurrency. It's important to be cautious when trading. Avoid transferring large amounts directly to your bank card online, as there's a high risk of fraudsters in the market. Even checking transaction history might not be enough. It's safer to deal with trusted individuals, especially for transactions between 10,000 and 100,000. Stick to trading with close friends who use their own money for coins, not for illegal activities. If unsure, it's best to stay away to avoid trouble.

When buying, watch out for monitored accounts. Trading with them could trigger risk control measures, leading to investigations and inconvenience. I recommend transferring money to a platform like Alipay first, then to Yu'ebao for a cooling-off period. After that, buy from acquaintances rather than specialized sellers to minimize risks.
