Bitcoin needs to scale or this problem will get worse.
Another cause of the delay is when our hot wallet also needs to confirm once we do a topup.
The system does not release funds till the internal confirmations complete as well.
Wasn't much of a problem before, but with network delays, its adding to the problems.
Withdrawal should not be a problem if u have confirmed fund in your hot wallet. All u have to pay fee as per current standard, i.e. https://btc.com/stats/unconfirmed-tx, if u want fast confirmation of withdrawal amount.
If u dont have fund in your hot wallet, all u need to do is send fund as per current standard as mentioned before. The whole process should not be delayed more than one hour in any way, unless u have your own process related constraint.
This medium post may come handy if u have accidentally created a low fee Tx - https://hackernoon.com/holy-cow-i-sent-a-bitcoin-transaction-with-too-low-fees-are-my-coins-lost-forever-7a865e2e45ba
We dont keep too much funds in trade hot wallet.
But we do pay more or same fee as recommended.
We double spend stuck transactions as well if over a certain time.
Wont be increasing the HW funds at the moment for sure. Only safe and manageable funds are stored online.
This is the main reason why we have set a disclaimer for upto 24 hrs on a withdrawal.
