An upcoming initiative we're planning on - slated for development in Q1, the integration of the Bitcoin Lightning Network. In the meantime, during periods of Bitcoin network congestion, we recommend using alternatives such as Litecoin for your withdrawals and deposits.
It's good to know that your team is trying to integrate Bitcoin lightning network despite its low popularity which goes to show how serious ya'll are about your site. Also, I am glad to know that other popular crypto like LTC are available for deposits and withdrawals.
Am looking forward to Bitcoin LN implementation in the near future.
