There is one important issue to keep in mind regarding the USDC and EURC USDC is a fully programmable geo-location, time and feature alt coin enabling full control over individual consumption habits.
Translating to real life e.g., the issuer of the coin witch is regulated by the government can restrict USDC you have to buy gasoline only within 100Km from your residence and up to 50 liter per week. same for food , leasure , travel for anything you purchase.
This feature is not in implemented yet as far as i know but its there. Giving you free money just the get used to working with USDC and later implement restrictions its something every user should be aware of.
