Is there a formula for calculating the profitability of investments for your project?

The splash of weight entering water faded some time ago, but the delicious ribbons of scent still travel. New sharks cruise in from farther and farther away, about as able to resist this bait as they are capable of literally walking away.

And yet. Most are cautious, milling in that endless F5 pattern we all know and love. They take sidelong looks at the bait. Are those faint metallic flashes within truly delicious coin... or just a barbed steel hook? A few rush in to bump it with insults, a few take tentative nibbles. The bait doesn't react. No trap closes. Curiosity grows. That wonderful curiosity, simultaneous flaw and strength. A few more bites are taken, the members of the milling mass speed up and tighten their circles.

I guess I'll join the pattern.

Be careful, we've got sharp teeth.
