When depositing with cryptocurrencies, you will be charged with a network and wallet fee in order for the transaction to take place. These fees are not made by Howl, and do not benefit Howl in any way. Fees are required for any transaction made on the blockchain.
The fees can vary with each transaction depending on the traffic that the blockchain has at that time; we don't have control over how much the fee/s may be.
Please ensure you deposit using the correct network, you can find out more about that here: How to deposit?
