USDCoin (or USDC) is a stablecoin pegged to the US dollar and issued on various blockchains, including the ERC20 standard in the Ethereum network. Such assets are characterized by high stability, wide acceptance and fast transactions, which makes them ideal for exchange operations. However, when converting to cash EUR, it is necessary to take into account many factors: rate, reserve, geographic location, payment restrictions, as well as security risks.
