We use a partner for crypto-fiat exchanging and currently we support Bitcoin only, 

Choose top up, and create an invoice. You will be shown a amount and a bitcoin address to send your bitcoin to. Make sure you get this exactly right and complete the transaction with the required time frame.

***** ONLY SEND BITCOIN (BTC) DO NOT SEND BITCOIN CASH (BCH) *********

The BTC are converted into FIAT by our third party crypto currency processor, and you are credited the fiat funds in your MuchBetter wallet.
