another thing that comes to mind is the bots
It is autobet much likely because when we said "bot" it is much more referring to a third party bot. Some sites dont even have their own autobet such as JustDice and some sites dedicated their work into refining their autobet with lots of feature like Betterbets
the third party bots that you can use on the site.
Third party bots has nothing to do with the difference between all these gambling sites because as long as the site release their API then anyone could run a bot there by either make your own or use an existing one. Seuntjie's bot cover up most sites around here so most sites / players use seuntjie's bot as their third party bot
Some casinos now even have funds in escrow to cover user deposits.
Huh? which casino are you talking about? never saw one
