Zpool web page says:
"Non-BTC payouts depend on that coin being mined as your BTC balance is traded internally by our system to your currency of choice."
Does that mean that if you mine an algo and reguest payout in a specific coin your coins are first exchanged in BTC and then BTC is converted to the specified coin? Or it applies only to different coins in the same algo?
Good question. The statement says it's done internally but doesn't say whether it's done in 2 stages. Analyzing the code
would answer that.
But, as Crackfoo said many, many times he's not a coder so it's over his head. That's why I suggested analyzing the logs.
That
is the job of the admin.
It's possible that coins get asigned initially a bigger value when they are placed at the exchange and then, when they are sold the value is adjusted to the real value.
Those are random events. Coins go up and coins go down, how could random error cause a consistent 20% downward bias?
Also returning to my previous point, it's of no value to speculate about how exchange works unless we know that exchange is
done in the baseline case, ie mine one coin and get paid in same coin.
