Today I have found additional 1000 satoshi at my balance as I understand it is some kind of bonus? How to determine where it came from? Searches for Dice history (because the last games I did with high risk), lottery tickets and so on do not help. It would be nice to have a section where you can see all the operations of receipt and flow.
Check your emails. If your account was inactive for a while we will have sent you a "We miss you..." offering you 1000 sats after you come back and complete 10 free rolls.
Is there a politics event bet for the UK election, hopefully it will be big enough event to get interest and bets on it going, the potential for wild card outcomes I think is maybe higher then ever before. Volatility is a bull market
Not yet but good idea.
There are bots that are very very cheap that solves captcha for you these days, I am sure the prevention doesn't come from captcha but from something else, hell I literally haven't solved captcha on this website for months now, I suppose when you solve enough of it the system makes you a person that is "human" and then you can use bots.
I don't know the ways they can go around and even if I did I wouldn't share it here for the reason that bad people may use it but in the end captcha itself is not enough, sure it is still better than not having it, not having it would result with a lot more trouble but see it as like a castle and captcha as it is walls, just because there is walls doesn't mean it will never be broken but surely it is better than not having any walls.
You're right, captcha is a very small part of the defences. Without it abuse would be so easy everyone would try it but it doesn't stop the determined thief. Kprawn was on the right lines. Manually reviewing withdrawal requests is the most effective way of combatting abuse.
