Generally speaking, it is normal that it takes around an hour for the “submitted BTC transaction” to be confirmed on the blockchain.

The BTC transaction would be pending due to the lower transaction fee.
If you find your BTC transaction is still “pending” after one hour, this may be the reason.

As all cryptocurrency transactions are executed on the blockchains, and once a transaction is verified and added to a block, it becomes an immutable part of the blockchain.
Therefore, transactions cannot be reversed, canceled, deleted, or altered by anyone, including SecuX.
This is a fundamental aspect of blockchain's security and decentralization.
However, for pending BTC transfers, users can increase BTC network fees after a transfer has been initiated.
