1  Economy / Computer hardware / Feeler - 750 Avalon 741 available on: January 03, 2019, 05:40:31 PM
Just throwing this out there to see if there is any interest.

I have about 750 Avalon 741s recently decommissioned in working order available for bulk purchase. (Thinking in the neighborhood of $25/unit)

Can be sold with or without power supplies. (Most ran 2x 750w HP server PSUs)

We can palletize and arrange shipping as needed.

This is a bulk sale only, I have no interest in piecing out lots of less than 250 units.

This is not a forum escrow deal, this is a sale from a licensed and registered business. You will receive a commercial invoice.

Units are available for inspection prior to purchase.

Please PM if you have any questions or interest. Flexible on price if all units are purchased at once.


Edit: RPis and AUCs are available as well. Will provide many spare AUCs if requested.
2  Bitcoin / Mining speculation / Bitmain announces a new 7nm mining chip - BM1391 on: September 21, 2018, 04:43:45 PM
https://bitcoinexchangeguide.com/breaking-bitmain-7nm-bitcoin-asic-mining-chip-bm1391-announced/


Well just when people think bitmain is down and out they seem to pull another rabbit out of their hat. Lab tests show 42 j/gh...if they can bring it to market around 50 j/gh then once again noone will be able to touch them.


Edit: I put this in speculation since the hardware hasnt been released or shown to actually exist. Didnt see the topic in the hardware section already. Mods can remove if necessary.
3  Economy / Service Discussion / A more robust mining calculator on: August 02, 2018, 08:38:55 PM
Nearly all bitcoin profit calculators you find are static to the current difficulty making forecasting nearly impossible.

Here is a new calculator that can actually forecast based on historical trends.

As with any calculator, remember to view it as a rough estimate and not the gospel.
