Every time I send OTC related messages, many people come to me to buy U. Isn't it good to buy U directly on the exchange? The exchange review is strict and difficult to buy, so let's make our trading records look better. How can we buy U more smoothly? My top trending tweet "OTC Knowledge Encyclopedia" has been popularized for a long time. If you insist on me selling it to you, your exchange cannot buy U, but you still want to buy it from me? Isn't that nonsense! I dare not accept the money you sent me for free. There must be money launderers and legitimate cryptocurrency traders among the people I refuse. I hope you understand that I have been able to achieve zero freezing until now because I adhere to my principles. One negligence could make all my years of accumulation disappear. A golden signboard is more important than my life. Even if a very good KOL friend asked me to buy U, I didn't give face. No one can break through my copper wall and iron shield.
