Prohashing seems to assume that the coinbase is the same as the miners' reward, which it is not the case for SmileyCoin. The word "Block reward" is used on your page, and shown as 10 thousand SMLY. But the miners' reward is only 10% of the coinbase.
It may not be as profitable as your calculator implies (apparently still very profitable, just not this much).
I looked into this and it was decided to discontinue the coin due to low-quality daemon software.
The scrypt blocks are returning an error about an "EIASAddress," but searching the Internet for the term didn't reveal any documentation as to what that is or how to create transactions to resolve it. More concerning, however, is that the daemon will return this error when scrypt blocks are submitted, but not when blocks for any other algorithm are submitted. It silently succeeds for those algorithms, still submits the block to the network, the other nodes reject it, and the daemon wasted over $100.
This lack of testing on the part of the developers is unacceptable. Real people's livelihoods are at stake here, and that was someone's salary for the day.
