There are constantly newcomers and novices entering this circle, and many people will consult about many simple questions. Some people are confused about buying and selling, and have been unable to buy U on the exchange. There are also frozen cards that are in a hurry and do not know how to deal with them. We have decided to open an OTC special sharing space every Friday at 9 o'clock. If you have any OTC related questions, you can come for consultation and exchange. See you soon.
