I don't see yet a crypto-gambling site that offers a lottery that becomes a success in the long-run.
On the other hand, if we take this on a physical lottery, yes the majority closed their service but even they continue to operate, I doubt people will be allowed to go to this place. Lining up in a lottery is defeating the purpose of social distancing and I doubt a community that put under lockdown will have the interest to throw some money to play on a lottery.
Have you forgotten about freebitco.in?
They are still successful up till now and they have weekly lottery on their site.
But I guess others don't really see's them as gambling site and only consider them as a faucet.
