I think people are living a fantasy if they think any of this is decentralized. If it runs on GPU's the big money has access to GPU's and puts up massive farms. If there are ASIC's the big money orders massive numbers of ASIC's and puts up massive farms. Big money is going to control the networks with the current POW or even POS coins.
That is why I find it interesting that some people are starting to think outside the box about the topic of decentralization, and not about the tools of the trade. Overall that is a positive thing and it will be interesting to see what the brain trust in the community comes up with.
about 400,000,000 million gpus can mine coins at a profit
even if ½ are on big farms and ¼ are on small farm that means at least 100 million pcs across the world can mine at a profit. and at least 50 companies sell pcs or gpus with 1 year to 3 year warranties
that is decentralized .
1 asic seller or 1 asic sellers selling gear designed to break in under a year is not decentralized. and if ½ go to big guys ¼ to smaller guys and ¼ go to little people with 1 or 2 asics you simply kill off customer base.
It is easy to justify buying a pc for 2k that earns 2 bucks a day while you sleep. no gpu mining you buy a shit pc for 500 or less.
Asics did not make 2017 the best year in mining profits gpus did.
I sold off some more gpus.
Still have 18 1080tis left I did buy a lot of LTC3+ I will not buy any asic on a coin being attacked. such as z9
I rathe use btc asic or ltc asic gear.
If I believe in a coin such as zcash I would buy some coins .
