I think Coinexchange will open DOGE if we just ask them, as there is a demand. You might give them the link to this thread and the discord link (which is a different new one I believe).
DVRS opened Doge market on CE. I think it was 1 BTC that team paid

but DVRs is too much of a supply, SBit may do very well for another 5-6 months or even a year if Doge market opens. It's just for now at 1 sat total cost of entire coin is 15 btc. Paying 1/15th of it for listing is kinda stingy.
