Can you explain to me why you're advertising a 0% house edge when in reality
that's not the case?You can choose to deduct whatever amount for the transaction fee - that is fine, but the amount should
NOT be deducted from the bet amount! Only the return if the player wins!
For those of you who cannot see the math behind it, allow me to fetch a quote by myself:
This means for a bet of minimum size (0.0005 BTC) the house edge is:
Win event [1/16]: return of 16 * 0.0003
Lose event: return of 0
ev: 0.0003
This means you lose 40% per bet - a 40% house edge on the minimum amount. That's pretty far from a 0% house edge, don't you think?
Even at the maximum bet: 1 BTC, there's still a house edge.
If you win, you are returned 15.9968 BTC.
This does correspond to a 0.02% house edge, which is far from the 40% earlier, but it's still not 0%.
(Though it's fair enough - this amount can correspond to a transaction fee, albeit it's a whopping 0.0032 BTC)
The deduction should only apply to the payout. Either do this, or stop advertising the website as as having 0% house edge.
If this were a website with 0% house edge, then when you bet 0.00060000 BTC and
win, you should be returned 0.0094 (which is 0.0006*16-.0002) instead of the 0.0064 that you DO return.
