Is there anything better to be mining than ISR? I figured IpoMiner would be focusing on coins that were pre-first-bubble, but perhaps I assumed incorrectly?
Sometimes after the first bubble pops, the network hash rate also drops proportionally so it's still moderately profitable. The only coin listed on IPOminer with a higher BTC/MH/Day is IVC, and I don't believe it has a large enough total network hash rate to support the entire pool's hash rate. If you're tired of ISR, I'd recommend switching off the multiport to a single coin's port and just watching it until IPOminer has found something that interests you again.
