They never shipped, I ordered on October 2017. And they were supposed to ship December 5th. Minerwarez continued to promise the miners for several weeks after this. Then one day they decided not to ship them and backed out of their promise to ship them and then offered the 821s at zero discount and they wouldnt ship until March. LOL!! Like bro, Ive already received 2 shipments from bitmain since then. GFY! Asked for a refund, then called my credit card company and they said they MinerWarez were fraudulent. I wont buy anything from Canaan EVER again.

Wow, thats very unexpected. And that is outright cheating.... U did get your money back right? What did canaan say about it. U did use an authorized canaan retailer right?

Theres alot of new customers and the mining space is growing exponentially, so yea. Alot of us that have been mining for years will be forced out if we aren't already or haven't been able to become a big mine with large working capital. Even then, we may not make it. Sorry guys, its just the way it is. We wanted Bitcoin to become universal, that means Mining will from now on be a very quick race to the absolute bottom of profittability. That also means that Canaan and Bitmain and other ASIC manufacturers of today will also feel the pain in a few years time. Newer hardware is coming, they know this and they are trying to do everything they can right now to make their last ditch profit. Because shit, they may not even be around in 2 years time.

This looks like it will be the case. In general, mining would be unprofitable for all if it goes this way. I wrote two topics on this recently. It seems that there will always be high difficulty increases because the average buyer does not take into account difficulty increases and other risks. News and media also push them into mining.

If this difficulty increase keeps up, the winner wont be the home miners or the big miners, the winner will be the fellow who just buys bitcoin and holds it. Why? Because difficulty rise up so much that even with the cheapest electricity, u gonna make more just holding bitcoin.

So,
If bitcoin drops = miners will make huge losses. Bitcoin holders make some losses.

If bitcoin price stagnates = miners dont make money because difficulty rise alot over time and higher cost miners switch off machines while lower cost miners make like 50-60 bucks per machine LOL. Machine will likely break before they break even. Bitcoin holders make nothing.

If bitcoin price rise alot = miners make some money. Bitcoin holders make alot more money

Asic manufacturers will still make money from selling ASICS but make nothing much or lose money from mining.
