I'm ok with such a minbet size, my only concern is with current market volatility the likes of the NZD shifted 5% over just a few days this week and 0.1EUR suddenly was 0.199775NZD, very close to requiring me paying a ~50% premium at 0.30NZD to meet the over the 0.1EUR rule. Right now it's 0.1938NZD.
What date does the conversion rate matter, on the date of the win or the end of the comp. Seems like alot of work for admin to confirm date of win and currency rate on that day etc but thats the most fair way because a qualifying xwin on day 1 not being valid on day 14 is crazy.
While people are free to feel I was getting a good deal playing 0.10 NZD they also fail to mention on other providers with weighted minbets(ie 10c EUR/USD, 20c NZD/AUD/CAD) I was paying a 10-15% premium over EUR players without complaint when my currency was stronger and they had an edge.
It's easier to just say something like:
10c USD/EUR/GBP
20c NZD/AUD/CAD
etc
Figure out the euro minbet for future slot titles in question and double it for NZD/AUD/CAD
