Wow! Congratulations Knehasen for winning $3700 from just a $50 no-deposit free chip! Fantastic!
And welcome to Askgamblers forum too.
I'm not familiar with Hera Casino and I think it's a restricted casino for me. Some casinos have no max cashout limits for their free chips, but most casinos do, and in this case, our Cocopop here has already confirmed it for you. It's a real pity that the most you can withdraw from that $3700 is only $200, but it's all free money anyway, so don't fret about it though, hehehe.
A number of casinos also require a minimum deposit amount of $50 in order to withdraw any winnings from no-deposit free chips, which I think is way too high an amount, so you need to know exactly how much you need to deposit to satisfy the withdrawal terms. You would only waste your money if you make an insufficient amount of deposit, and still couldn't withdraw your big winnings.
The best thing for you to do, is to read and check out the Bonus Terms carefully yourself. Answers from Live Chat hosts can be wrong and misleading at times! Like in this instance, you were told the wagering would be 20x, but Cocopop was informed that the wagering would be 50x instead. See what I mean?
Also, it would be best if you make a deposit (say $50)...but DON'T TAKE ANY BONUS with that deposit! Taking a deposit bonus would only incur more wagerings for you to do, which is not what you want!
The wagering requirement on a deposit (no bonus taken), before any withdrawal can be allowed, is just 1x the deposited amount, so you may only need to wager $50, then you can withdraw $200 from your earlier no-deposit winnings!
Do not believe everything what the Live Chat host tells you...they can be misleading...because they do not always know the true circumstances or situation of your game play...they always reply 'by the book' answers...if you know what I mean.
As a new player, you need to know, learn and understand a lot of new things, particularly about casino's Bonus Terms and their Terms & Conditions. One small mistake and you may lose thousands of Dollars in winnings!
