@Herbert2020 I think your question has been replied to many times already. Implementing native Segwit would be very difficult to do because of the way indexing is done. I guess a lot of us would like it too but for me, the withdrawal fee is already very low, even compared to Segwit sites!
you misunderstood my question.
i was not asking about "user's deposit addresses" but the very small number of addresses (basically the 2 main ones) that the "site itself" is using for consolidating inputs from user addresses and payments. and i posted those two addresses already. i don't think there is any need to index anything if they simply change the old 1Fu... address to a bc1q address, specially since payment handling,... should be happening as a separate module.
