Just a caution to every player not to withdraw BTC using the native chain for now. Even though I chose the slow option which deducts BTC0.000075 withdrawal fee, I still expected it to be done within the next two hours because I've seen blocks confirmed with fee as low as 2 sats/vbyte and not 23 hours. I later found out that they send by batch and that's probably the main reason why it took that long.

I know it says 'within 24 hours' for slow withdrawal but I still think it's poor service given the fact that the network isn't that congested.
