Sir, my ethereum is pending since 3 days before. I want to know when complet my transation. My hash 0xbdcebd75a56d82f27528166923b818ce3f743f4093736900d56f65d17e3791e5. What can transaction lost permanently
Generally, a transaction should show up on Etherscan or any Ethereum explorer within minutes, and confirmation should be done within an hour (the confirmation time depends on the gas price you paid for). If the transaction isn't showing up after 3 days, it means your transaction didn't get broadcasted to the Ethereum network.
You should resend the transaction again. Since you mentioned you're using Bitbns wallet, your ether balance on Bitbns should remain unchanged as the transaction didn't go through, if this is not the case, you should ask Bitbns about this.
