Obviously, law enforcement could simply ask the casino what happened to the deposit, and could then continue to track the history of the coin you received.
Oh, OK.
Since I play poker on fiat sites, I wasn't thinking about that.
Of course, I realized that a long time ago. When you deposit, at least in the crypto casinos I have deposited in, you deposit in one address and when you withdraw, you get the money from another address which is the one they use to consolidate inputs. Normally if you deposit today and withdraw tomorrow, probably the money in the address you deposited will still be there, without consolidating.
Anyway, I think this excuse is bulshit, and even more if we talk about 300% of wagering requirements, so the probability of losing your deposit will be close to 100%, because we can say that some people use casinos to launder money in the same way that we can say that some people use mixers to launder money, and in case we want to investigate, we could follow the trail with the collaboration of the casino.
Honestly, I would never use Roobet and I have no idea how these online casinos are getting away with stuff like that. One thing is having wagering requirement for bonuses, but up to 300% for deposits is just crazy. I worked in the industry for years (brick&mortar casino) and stuff like that simply wouldn't fly there. At least that's how it was in Croatia when I worked there ~15 years ago, maybe Las Vegas and places like that are more strict when it comes to that.
Responding in no real order:
In US casinos if you are cashing out more then a certain amount they will check your ID and fill out paperwork. If you go to a table and drop cash & get chips and don't play more then a hand or two it's not a big deal unless they notice you doing it more then once. Then they will ask you why.
Years ago, as in before BTC existed, most internet casinos had a 2x playthrough requirement (200%). After BTC and online gaming became really popular the numbers went all over the place.
As for the 25% to 300% I can see them doing that based on how long you are a member there and how much you gamble.
It's really a quick and simple way of stopping people from using the casino as a mixer.
New player, puts in $50 then fine 25% playthrough. New player puts in $10000 yeah, you have to run it through twice.
Player who has been playing for years at regularly deposits $1000 a month. Puts in $1000 no playthrough required.
I'm sure somewhere in their management offices there is an excel spreadsheet with the general amounts.
Most online poker rooms don't have a playthrough requirement but I have seen some that do. Usually 100% for new players and slowly dropping as you use them more.
If Roobet has 1000 customers and 995 don't care about the playthrough then they don't care about the last 5 if it makes them less appealing to people who are trying to mix their coins there.
