Just from experience if I try to withdraw using Tron network, within 2-3 minutes max I think it will be credited onto my desired wallet. I don't think the recent issue with Oldbear would just be a network congestion especially if he picked a chain where there's common issue of delays like Ethereum. Well, it has been handled already and probably just worried that it didn't came in an instant. Beginner's dilemma.
Actually, aside Bitcoin, the other network options I do use is TRX because it is very fast and I use it for deposit so it would be confirmed so quickly for me to play my game. I literally do not like network delay when it is time for my game that is why I don't waste my time outside Bitcoin and TRX because of the speed at which it is confirmed. Network congestion is not my thing so I avoid it as much as I can whenever I want to do a transfer or deposit.
