# What happens when I run out of green coins?

Master users who have already spent their 300 Green coins and SLAVE users who wish to purchase RFT Services can carry out the purchase of RED coins through their Helpdesk panel in the amount necessary. At completion of payment, these coins are added automatically to their account and can be transformed into GREEN coins through the Coins Converter in their account.
