Correct me if i am wrong, but crypto casinos usually have pretty good revenue, and $4 millions shouldn't be hard for bigger ones like metawin, and they are even getting it back.
Here's their latest volume according to dappradar:
Thanks for this. I forgot about dappradar tbh lol. Though, it appears it only displays the ETH chain and metawin supports many coins so it's likely more than this, too. I personally prefer cheaper alts like LTC, SOL, MATIC if I can help it.
I mean metawin is giving away >$700,000 weekly with their race prizes!
Also watch out for the end of the year event. Metawin is set to giveaway 6-7 digits in USD. $500K is starting point. Official announcement is very sooon.
