but I think it won't change anything if the dev lists DOGE. Deposit and withdrawal via LTC is near free, so adding cheaper alternative is just too much work (with little impact).

We closed Doge down because it was never profitable and we were encountering more and more problems with the Doge core software being unreliable. The code hasn't been maintained for many years there is no hope that will ever get sorted out. There has been a long delay paying out final withdrawals for the same reason. Our Doge node crashed and required rebuilding. The latest update I have is that it has finally stopped crashing and is about 50% way through resynching the entire Doge blockchain.
