1. Nai Zi Ge made five withdrawals through the backpack, and on the third withdrawal of 30000 yuan, he asked for the source of funds. Nai Zi Ge submitted a withdrawal record for Binance and quickly gave it to him. The other times, he did not encounter any problems and quickly withdrew today and received the funds tomorrow. 2. In addition to the experience of withdrawing funds, what Nai Zi Ge wants to thank is that BP specially hired a young man to accompany Nai Zi Ge to open a bank account in Hong Kong. Nai Zi Ge just casually said a few weeks ago that he wanted to buy some Tesla, and BP took it seriously, always worrying about helping Nai Zi Ge. 3. Nai Zi Ge has tested three compliant exchange withdrawals, coinbase，kraken,backpack。 The problem with CB is that it works from seconds to small amounts, but it doesn't work for large amounts as it will get stuck. The Kraken problem is that it takes a long time, at least three days, and no one can be contacted. Backpack arrives the next day and provides excellent service. If you encounter any problems during the withdrawal process, you can quickly contact them through Twitter and the community. 4. During the process of withdrawing money, Nai Zi Ge clearly felt that Backpack was a real person, doing real things.
