Which companies will adopt it and which ones won't is probably hard to determine from the outside. It should be a fairly objective evaluation though internally for a company in terms of what hardware the company currently has and what it will cost to farm Chia and what future expected value for Chia may be. Chia has somewhere between 300K - 400K full nodes operating on the network. That is objectively more decentralized than Bitcoin that has somewhere on the order of 40K - 80K full nodes the last time I checked. So I would say Chia is the most decentralized network I currently know of.
> The payoff for the lottery is HUGE. So even though the EV is negative, people still do it. The payoff for Chia is comparatively small. People won’t (and don’t) care.
That will be a function of the price of Chia. As Chia's price increases more and more people will want to get into that lottery. A lot more people will consider farming some plots of Chia if one XCH is worth $50K compared to $250.
