Worldcoin has a 15 second block target, so it gets a huge number of orphans and blockchain forks. I just wouldn't recommend mining any coin with less than a 60 second block target. But if the coin still makes profits even though you are getting a large number of orphans then why not.
And yes calculators will not factor in orphans. The calculators are designed for litecoin where orphans are extremely rare. Worldcoin by design (flaw) will have orphans like mad.
Also do note: you may not get any orphans showing up in your mining software, but the pool itself will be getting lots of orphans. So even if your software says the orphan rate is like 2%, the pool itself may be getting 15-20% orphans.
true exactly.
Also I won't mine on anything less than 60 seconds either. Even that I feel is pushing it, I got orphaned a lot on CNC.
but like you said, sometimes in the beginning and when difficulty is low, if you think the coin has some future, you should calculate your valid share % vs your hashrate and decided whether or not its feasible/good idea to cop a lot of (x)coin.
