The profit calculation on multipool.com is different from coinchoose.com and from coinwarz.com. Why? How can I be sure that I am always mining the most profitable coin, if there are different calculation results?
Those sites don't account for stales and such due to fast block times. Multipool does.
If a coin has 20% stales because it has 10s blocks, the calculation coinchoose/coinwarz has is way off (by 20%).
