So this is the profit (before other expenses) for exactly 1 day?
How high are "other expenses"?
Even if these are $34 per day, this already puts us roughly into the "very optimistic" category from above with a sound 25%/year ROI.
Definitely a promising start!
If I read correctly, I think the company is in the US and the books are USD. Don't forget to include taxes in the calculations. I think you'd have to find out the tax rate from the Ziggap folks, as it's an LLC and taxes pass through to the owners in most cases, thus making the rate dependent on their other income sources if any.
