There are a few different limits when buying stablecoin. All limits can be seen in the interface. 

There is a minimum and maximum limit per transaction. The minimum per transaction applies to the amount of USD used to purchase stablecoin after fees are applied. You need to pay from your Payoneer balance a bit more than the stated minimum to account for the fees. If the amount you enter is below the minimum or above a limit, you’ll see a message before you can proceed. 

In addition, there is a limit to how much stablecoin you can buy with Bridge daily and monthly. This limit applies only to buying stablecoin. The daily limit resets at midnight UTC each day. The monthly limit resets on the first of every month.
