I cant believe it. They shipped the chips first. We will never reach ROI now.

For batch-3 devices that are delivered soon, you're looking at a 3-4 month ROI. Not bad, but not great. Any significant delay will kill that ROI as lots of hashing power is coming online late this year.

Can you provide a spreadsheet of your calculations? I believe you are way off and not even in the same ballpark.

I think he's right, actually.

This is incorrect. A 4-module unit cost 100 btc and the exchange at the time was around $72. You entered $7200 cost for the 3-module machine.

Actually that was the defaults for an Avalon, so blame the page. In any case, if you want a return in terms of BTC you should be running it against what 100 BTC can buy today, meaning the cost of a 4-unit should be priced in dollar terms as just over $9k. Some calcs make this easier by allowing you to price cost in BTC too, but Coinish is down right now.

There's your figures for an Avalon 4-unit, even worse:
