Fwiw Metroid, this time you might be the troll.

Grin has been designed to support GPU with a phase-in of ASIC over the span of 2 years. I have several GPU's switched over to mining Grin and also one of the Sapphire cards.
ROI is 40 weeks or so as I running in in C31 which is the ASIC friendly algorithm. It's very ironic that a GPU is making money using the Grin ASIC branch.
Here's a breakdown of the algorithms and phased rewards. Yes it's in geek talk but these who understand will figure out how to make money.
