The demand is not about 400k dollars but about 400 million dollars, that is what is making people nervous about what it may happen to stake, if the amount that was in the demand was as high as the number that you are giving then I'm sure that many people will probably not care, but when the amount is so high this is making people nervous, because even if stake is probably one of the richest cryptocurrency casino that we have around I doubt they can afford to pay such high amount if they lose.
Stake customers should not be nervous, even if the case become very serious, customer's money is protected. They are not dealing with scammers, but with a legal battle in the court. It is a court case, people do not have to be worried. Be it anyway it ends, Stake customers are still going to increase as the gambling site progresses.
Both of you are right, $400 Million can be a small amount to Stake.com and that same amount can also be seen as a big amount but that depends on which angle you are trying to see, and currently Stake.com has a net worth of more or less $1 Billion dollar. So, we can somehow say that in any case, Stake.com won't pay that ridiculous amount as a settlement for the said lawsuit and it is already expected that they will try to make that settlement go to a much lower amount where it can be described as a reasonable amount for the both sides.
400 million dollars is not a small amount of money, not at all. But has there been anything like the court saying that Stake should pay the amount? No. I am not expecting that as well. Even if Stake is truly at fault, the court can not make it oay such huge amount unless certain things are considered first.
