I have been looking at these asics for a while. I want to get another mining system that is a good option while continuing to GPU mine. my GPUs mine Eth and CPUs mine XMR and with a Z9 I would mine whatever equihash coin is most profitable, probably zcash. but At 2000 i have to save and get my wife's permission to buy it, lol. That is not gonna happen cause our 2nd car just blew up a few weeks back so now there are more important things, in her book. but as people were saying GPU mining is more decentralized due to the fact that every gaming system can mine. but not everyone can drop 2000 on 1 asic miner, but its easier to afford one GPU and slowly expand like i did. I started with one GPU and bought another after 3 months. MY rig is building it's self. I just bought another RX570 2 days ago for 288.00 and my rig will make that back in less then 1.5 months. I thought its was a good deal until the next morning when i seen the same newegg item number for $38 cheaper, I called newegg and asked if I could be included in the sale so then he requested a$38 gift card for my to balance the difference. its the asus rog rx570 260 @ newegg on sale until monday. so quick go click click. lol

so i would have to agree that asic mining is more centralized because of the conditions they need to operate and their cost. I am wondering if they get as hot and loud as the other antminer asic miners??? I want a couple asics and a few mining rigs. trying to keep a balance but the GPU rigs come first since its cheaper. GOOD for winter though, I heated my apartment with my mining rig all winter. my space heater paid me. haha.
