If you are crediting into your Gatecoin account from another exchange or wallet and your transaction is still unconfirmed after several minutes then it probably means that the network/miner fee that you have paid for this transaction to be processed is too low.
The Bitcoin/Bitcoin Cash/Ethereum miners will always process faster the transactions with the most important transaction fees associated with them, as one of the ways miners get paid for their work is by collecting the fees on the different transactions.
So, naturally they would prefer to include the transactions with the highest fees first. If your fee is high enough – your transaction will go through faster.
As a result, when crediting cryptocurrencies on Gatecoin, please make sure that you have sent the funds with an appropriate fee. For Bitcoin transactions, you can check https://bitcoinfees.info/ for more information.
Note that withdrawals from Gatecoin to another wallet are subjected to a standard fee that will be used to pay the miners.
