well, if the casino is already established and strongly running indeed that there will be no bankrupt to happen , but those newly operated and sadly experienced a Huge win from new players, in that sometimes comes the dishonesty from the site and turning into not paying and become a scam one.
but with Roobet.com that has already tons of funds inside, Am not sure if any whales can make them bankrupt , not at least from my knowledge and understanding .
There are lot of such casinos turning scam after accumulating funds from players through lot of ways but we should focus more on our Roobet discussion as they are doing quite well and running smoothly from past few years so hopefully they will do it in the future with more boost.
