It looks like any ending in 25 seem to be, but the calculator tool says it is valid as less than 64000 2x exit point.
Thanks.
Sure thing. Martingale [EXIT] places 0.001 wagers when playing with BTC, so starting with your deposit of 0.00700425 it will try to place a bet to reach 0.00800425. Now, the special thing about EXIT compared to the other Martingales is that it quits early, as soon as your balance isn't enough to reach the next prize step. Each step adds 0.001 to the target outcome.
With the wager settings (425 satoshis, 1.019 multiplier, exit 2x wager, which is actually the default), in order to go from 0.00700425 to 0.00800425 you need to win 0.001. Since the win multiplier is 1.019 you'll need to bet ~0.0526, which, if you win, will give you 0.0526x1.019 ~= 0.0536, or 0.001 more than you have bet.
But you don't have 0.0526 to bet, only 0.007, so the EXIT is triggered. It's a refund because no wager was ever placed.
Hope that clears things a bit
