Step 1: Find your transaction hash (TXID)
Open the withdrawal history in the wallet or exchange you sent from and copy the TXID. Paste it into a blockchain explorer for that coin and check:
- Status: pending, confirmed or failed
- Confirmations: how many blocks have confirmed it
- Destination address: does it exactly match your BC.Game deposit address?
- Amount received after fees
No TXID at all? The transfer may not have left your wallet or exchange yet. Contact them first.
