Thank you teacher @yohan2on for the time you take to review my homework, at the end of my work I talked about the USDC, I should have delved more about the currency, if you gave me the opportunity to add more content to my article to improve my grade I would appreciate it, I am enormously committed to your classes, and I would appreciate it if you would give me the great opportunity to make amends for my failure. many greetings and blessings, thank you for your time.
