Why USDC and not regular USD or other currencies?

Using USDC stablecoin combines the familiarity of the US dollar with the technical advantages of crypto. Regular USD (like the money in your bank) can’t directly move on a blockchain – it requires banks and payment processors (which only work during business hours, weekdays, etc.). By converting USD to USDC, SI Predict enables instant, round-the-clock transactions in a digital form. Other currencies or coins (like EUR, BTC, etc.) aren’t used on SI Predict because the platform wants a single liquid currency for all markets to avoid fragmentation. USDC, being dollar-pegged, is accessible and stable for a global user base, whereas using a volatile coin would add extra risk (your betting currency value could change independently of your bets). Moreover, USDC is one of the most trusted stablecoins, with reserves backing it, which adds confidence that 1 USDC really equals $1. So, practicality and user protection are the reasons USDC is the exclusive currency on SI Predict.
