So there is a second lottery at coinpot since 2 weeks i found: the conversion rates.
I converted 1 token a few times to dash within one minute and got those rates:
Conversion from 1 tokens to 0.00000114 dash
Conversion from 1 tokens to 0.00000115 dash
Conversion from 1 tokens to 0.00000129 dash
Conversion from 1 tokens to 0.00000108 dash
Conversion from 1 tokens to 0.0000013 dash
Conversion from 1 tokens to 0.00000129 dash
variance is nearly 20%
A funny new game at coinpot?
Isn't this a good thing? They are giving you market rate every time. Would you rather the price be fixed for one minute? You're doing 1 token conversion for the challenge bonus? If you are, then you'll have to live with the real time exchange rates. I don't see a problem with this... DASH isn't BTC and the exchanges can be volatile. You'll get your token bonus with the challenge, so you're in a net positive. I see the live exchanges rates as a good thing.
The price of DASH isn't going to be making >10% moves in a matter of a few seconds. I've tried the same thing with Bitcoin and you also get these huge differences in the exchange rate. This isn't about the price being volatile, it's about Coinpot wanting to take a bigger cut from conversions. They're within their right to do this but it is just greedy.
The truth is closer to 14% based on the figures dabbur gave. I'd suggest you try converting 10 tokens at a time. You have to take into consideration that they round down so it can produce results that seem unfair to the faucet participant. I know how quick you are, but 6 1 token conversions would take me at least a minute (and you have to wait for the conversion lookup which can take longer during prime time).
Here's a sample of the DASH/BTC price action on CoinBase Pro. I don't people take a moving conversion rate as a sign of greed.

I do see rounding down an issue and they should consider banker rounding or some sort rounding that rounds down and rounds up sometimes so there's a better distribution amongst coinpot users while mitigating abusers.
