For example, is there a time thats set for Daily payout on the site?
Also, say hypothetically the daily payout is every 24 hours, would that mean if a particular crytpo coin was profiting well druing the first 8 hours of the 24 hour period before payout occured and then the coin slumped in value hugely, for the rest of the 24 hour period before pay out....
Would those crytpo coins, therefore be exchanged and paid out in BTC, at their current(hence lower) value? And therefore not converted to BTC at their most profitable value during the hypothetical 24 hour period?
I'm not sure what you are asking about. Payouts are not based on some calculated value, but on the real value which the pool got from mining coins.
We mine a coin -> we wait until it's matured and we're able to send it -> we send it to an exchange -> we exchange it into BTC -> we withdraw BTC from exchange -> we pay out to users.
Of course every block can be exchanged at different price, depending on what the best price was available at the time of exchanging. If a coin had a price 1 BTC in the morning but 0.5 BTC in the evening and we mined a block in the afternoon, then of course we will be able to exchange it for only 0.5 BTC because 1 BTC price is long gone. Or maybe you know some method to exchange currencies using either prices from half a day or current prices, whichever you find suitable. I could use such trick! ;-)
