In some cases, Bitcoin and other cryptocurrencies can be reversed and the transaction will be refunded to the wallet it came from.
Those reasons could be the followings:
- When the sender sends the amount of crypto less that the actual required amount.
- When the transaction is delayed more than 30 minutes and the rates have been changed.*
- If the sender sends the cryptocurrency to a different wallet address that is not supported for that type of crypto (e.g. If a user sends BTC to a TRX wallet address etc).
*We might ask for the additional fund in this case if the transition rates got updated and now it requires more funds to complete the transaction.
