Wish I researched before hand and didn't start gambling on Bitstarz. Similar story to btcgmbling guy...
My initial deposit was 0.58 bitcoin (or over 300 euros). Received 100% bonus with 40x wagering requirement as promised. Got lucky, won a few bigger bets on slots. My balance grew up to 9 bitcoin at one point. I was so happy, wanted to cash out it as quickly as possible, therefore I raised my bets up to the max. All the time while betting I was monitoring my balance and wagering indicator in %. Everything went smooth, and within few hours I managed to reach 40x requirement with over 6 bitcoin in my balance. Decided to cash out and went to bed. Just to wake and read an email from Bitstarz that I breached their terms and conditions of betting more than 0.025 bitcoin per roll, therefore all my winnings has to be forfeited. There's so many ways they could make it right, but they simply refuse to do so. They could make their platform so that it wouldn't be possible to make incorrect bets. They could make so that bets over the limit wouldn't count towards wagering requirement. Even after the fact, they could discard just the offending bets, but leave the other. But instead what they do they just steal your rightfully earned money. I feel like someone had stolen money from me.
Yeah that sucks man but bitstarz has pretty restrictive bonus rules and as such you really have no recourse. They do list the bonus terms and conditions with the max bet rule on their website. It could definitely be easier to get to but they do have the terms listed on this page:
https://www.bitstarz.com/promotionsThen you have to click terms and conditions and find rule 12 which states
Until the play through requirements have been met, the maximum bet that can be placed is 5 EUR/GBP/USD/CAD/AUD, 50 SEK/NOK. When it comes to Bitcoin players the maximum bet is 25 mBTC (0.025 BTC). This includes double up wagers after the game round has been completed, for example, wagering winnings from X game round on red/black.
Now for bitcoin players 25mbtc max bets isnt that restrictive. However if memory serves they chose this amount when bitcoin was in the 200s but in todays value is close to a $12.50USD bet per spin. Now in my online history have I rarely bet close to that although once on one of those Booming Game slots @ bitcasino I had just loaded a deposit and used a bonus and inadvertently max bet 96mbtc. Luckily it was a small winning spin where I got my money back but if they had restrictive terms I would have been toast right off the bat.
With that said its not all that uncommon for some of the big online casinos to have these types of max bet terms in place. Anytime I play somewhere new I make it a point to read their Terms and Conditions. This all comes with experience playing online however.
Sorry you got your winnings taken away and at least now you will be more aware next time you decide to use a bonus at any online casinos in the future.
