Hi!
I have 12 Radeon Pro Duo, 32 GB. Awesome cards and perfect for rendering. They also mine 50mhs per GPU. But nowadays it is not so profitable.
any idea what can I do with them? How to use them better? How to have more profit?
I mean other activities like rendering or whatever
Those GPUs are actually pretty rare and pretty expensive.
My suggestion is for now to put them on hold, if mining doesn't improve then sell them around Christmas time. Usually many people buy GPUs as gifts during that time.
