@denis can you verify if the Bitcoin fee is updated or outdated?
We have been paying rest of the fee (anything more required than 5000 sats) till today but we just have adjusted this to 0.001 BTC. I know this doesn't sound good but prior to this change, we have paid a lot of fees from our pocket. We will adjust the fee again once on chain fee changes.
It's a huge jump from 5000 sats to 100000 sats but if we consider the current transaction fees, it is logical. Btw is it possible to make the withdrawal fee dynamic? Instead of it being fixed at 0.001 BTC, is it technically possible to be dynamic? e.g. when the transaction fee goes down, the 0.001 BTC fee goes down too and when transaction fees rise, so do the withdrawal fees on your website.
It's best to stick with LTC, Doge etc since no one in their right mind would want to transfer BTC unless the amount involved is huge.
Many people don't mind fees and still use Bitcoin. Especially people who use software wallets like Electrum where they have total control on their funds and also have low number of inputs and outputs, fees don't affect them hugely. Btw I expect many people to move on altcoins to withdraw their money.
