Welcome back. Why the total removal of 200,9 ?
In fact, I'll probably return 200,9 variant later, the main reason is different optimization methods, it was too hard to put this solvers in an old miner. And, another reason is an asic's of course.
Hey, just wanted you to know, there are still GPU mineable 200,9 coins out there, even with the onset of ASICS. Komodo's new all Z-Address asset chain, PIRATE, is still mineable for me with a single GeForce GTX 1060.
I made about $1 USD worth in 3 days in a pool with a 5% fee (it is current the only pool for it) with on and off mining and averaging around 260 Sols/sec while on. Yeah, it isn't much, but what do you expect for a single graphics card?
I know ASICS have made 200,9 coins less profitable for GPU miners so it probably isn't on your priority list of improvements, but it is still doable for some coins and I would like to see it on your miner again.
