I don't understand what has to do the bitcoin price with the minimum amount to bet on a website?
For example I own a roulette website and I use "bits" as currency.
Minimum bet on our roulette game is 1 coin (bit) and maximum is 25000 coins (bits).
Looks like you use MoneyPot? People love to use the same chip values in different casinos. When chip has different value, them preferred casinos with more comfortable environment.
Chips in all casinos should have equal value. Because it's chips, not bits or mBTC or satoshis.
No I don't use Moneypot.
From what I see Moneypot uses "bits" as currency.
What you want to say is that some casinos use different exchange rates (and give more or less chips to players)?
