I think most mining hardware sales is going to be B2B not B2C anyhow... if you are not looking to go "big" in mining one will have to take your ball and go home at this point.
I slightly disagree. There will certainly be economics of scale and the fact that companies can actually "move" to locations with superior mining conditions. But I think there are a lot of opportunities out there for small scale operations, like the availability of limited excess power which allows a better cost structure than large scale. The question is what strategies the hardware suppliers will follow to place themselves competitively in the market and how they will try to reach and serve their customers.
But yes poor customer service and management is the problem here and likely they could careless at this point given the remarks Yifu made. Alternatively the DIY or chip only fabricators will also push the marketplace. Given Avalons failure I can't see many people wanting to risk it.
Yes a good point. Many "DIY" resellers got burned by relying on avalon and will want to switch to a more creditable supplier in the future.
