Jazz/ABC/Nitro - Pretty obvious. (I did hear about a couple payments very recently at Nitro...maybe some NFL crypto inflows there but feels like all 3 are in trouble)
BetWhale/WagerWeb - haven't used either in ages.
Heritage - Honestly haven't heard much either positive or negative lately.
One comment about Everygame, and I would be the last to defend them as I cannot stand them but being fair about it...for a small rec player, probably not that bad. Interface isn't bad, payment limits are not going to generally effect that player, bonuses are usually 100% or similar. But, if you have built your balance up (or are just a larger player, sharp play limited fairly quickly), the slow pay slams down. Nothing has changed, they have always had that pay structure. $2500 after several days of waiting, then 7 before another request. Effectively $5K/month limit. So, cannot go into that shop planning on betting anything above maybe $100. Waste of time. But again, small rec guy that wants $50 on the game, probably not terrible. Now, if he hits that 8 game lottery ticket parlay for $20K, enjoy your 4 month chore of getting paid.
