Bitso offers an Earnings program that lets you earn up to 4% per year for holding your USDC balance in your Bitso account. Earnings are calculated on your balance and credited directly to your account.
How to sell your USDC for your local currency
In the Bitso app, choose Buy/Sell, select USDC as the currency to sell and your local currency as the currency to receive. Once you confirm the transaction, you'll receive your local currency and can withdraw it to the bank account of your choice.
