It's all unsafe, it's better to open a card in Hong Kong, that's the safest!

Recently, several of my friends have made good profits due to the good market conditions. They wanted to withdraw cash for consumption, but their cards were blocked when they tried to withdraw money. The following is a summary of some of my own understandings on withdrawals that I would like to share with you.
1 Reduce the frequency of withdrawals: Try to reduce the frequency of withdrawals to reduce the probability of receiving black money. If you must withdraw money, try to make large-amount, low-frequency transactions and avoid frequent small-amount transactions, which can reduce the risk of being controlled by risk control [^0^].
2. Choose self-selected transactions: When trading, you should choose self-selected transactions or bulk transactions. Do not choose quick transactions, because you do not know which C2C merchant you will be matched with in quick transactions. The system will default to the highest price when you sell and the relatively low price when you buy. However, these two prices are often the most risky [^1^].
