Regarding the Multiply BTC bonuses, do I have to wager 25 times or one-time if that amount is the same or exceeds the criterion? I wagered 0.0005 but the below keeps showing up. I only claimed 1000 satoshis.
I don't understand your question but I'll try and explain what it says in the bonus terms you agreed to.
You have to wager 25x the amount of the bonus account and only 10% of that amount is counted in any single bet (except jackpot bets where 100% is counted).
So with 0.00001000 you got a bonus of 0.00001000 making a bonus account balance of 0.00002000.
0.00002000 x 25 = 0.00050000 is the amount needed to be wagered.
