Goldbit:

Assume Altcoin/btc spot prices are:

8:00:00 500 Altcoin/btc, is profitable, and added to the mining pool
9:00:00 spot price is 475
9:30:00 spot price is 450
10:00:00 spot price is 500
11:00:00 spot price is 600
11:30:00 spot price is 400
12:00:00 spot price is 375

Let's say that 50 Altcoin is mined at 9:00:00. Confirmed at 9:30:00. Exchanged for BTC at 12:00:00. What time do you want what posted?
