A very standard 4th deposit offer in terms of amount awarded (100%). However, I think Bitstarz is too conservative with its cap for FIAT users. This second bonus is also capped to €100. But if you play with BTC the limit is much higher, 1 BTC. Slightly smaller than the other deposit offer they have, but I would say still pretty good.
as 4th deposit the percentage of the bonus come back to 100%! Enjoy another great bonus on your fourth deposit up to €100 OR 1 BTC, credited instantly to your account!
