I'm not sure that the organizer of the bitcoin lottery will pay you a big win, so it's better to play state lotteries, where the payout of winnings is guaranteed by the government.
Most of the gambling sites mentioned in the OP still have their reputation at stake and it's unlikely for them to run away with the prize pool when they could make more money in the long run by hosting more lotteries.
stake.com bitsler.com bc.game is a place that I admit is comfortable, and the response to errors or whatever is very fast in service. bitsler I frequent with all the games I play often dice often gives me an advantage. and almost every day there will be coupons, big events are always there every day. You can check it yourself on the website I wrote..?
Stake and Bitlser can't be added to the list even though they're hosting something similar to a lottery, the big difference is that it's in a form of promotion that requires wagering rather than buying a ticket straight up.
Also, did GreenSpin close down, or were they just having a downtime since I can't access their website.
