Just for the record: I did get paid, twice. And i did get my refunds, also twice. I really have no reason to think this is a scam.

Fact is that lowering the payout to 1,5 or less or changing the min.deposit again doesn't make any difference. It only affects the time it takes to slow down and finally stop the system. Do your math.

I had three reasons to stop playing:
After my last refund OP raised the min.deposit to 0,1. Too much, I think.
Second reason: there were already too many pending transactions. The momentum was gone, it was obvious the system got (or was going to get) stuck. As all these systems do after a while. The earlier you jump in, the lower the risk, providing you quit at the right moment.
Third reason: The MakeBTC-debacle made me very cautious about sites that suddenly disappear. To be honest, I really don't know for sure whether that story was true, but like this one there was the story of the site being reported as a scam, at a moment there was absolutely no reason to think it was a scam. MakeBTC didn't fight back (scam???), BitDoubler did and came online again - kudos for that! But it p****s me off when people try to interfere because they want to "protect" me (and other players) from losing some money. Like I posted earlier on in this thread, I think it's quiet arrogant to put yourself in that oh so correct position and even worse: it affects the risk I'm prepared to take with playing this game. Leave us alone. You're not protecting, you're spoiling.

That said: I'm afraid that right at this moment I'm losing the 0,04 I earned here. At CoinPayoff...  . Yep, I jumped in too late, didn't do the math...
