How long need to continuously mining bitcoins on coinotron to get full rewards

[neuromancer56]

I've been used to seeing rewards fairly quickly for mining other coins on coinotron, but much slower response when mining bitcoins there.   I see a round length of 267 h on the site, compared to :3 hours or less for other coins.   Does this mean I have to mine bitcoins for 267 hours straight to get any rewards?  Or in other words how long do I have to mine bitcoins for at a minimum to get a full return on my mining time?   I'm not a pool hopper, but I don't want to mine for more than a day just to get full credit either.  I don't mind if the rewards are delayed but I don't want them to be reduced because I wasn't mining long enough.

Put another way, what does the 267 h round length mean?

I always felt like coinotron is suitable more for alternative currencies like terracoin or litecoin than btc.

BTC pool at Coinotron is pne of smallest pools, so 267 hours for a block is not unusual.
You don't have to mine continuously on BTC pool to get reward, but you must wait until block is found. And if pool had bad luck, then part of your reward will be paid in next rounds.
