That happened to me last year with Poloniex and Authenticator.  Contact the exchange, they usually require some info from you.  They will eventually deactivate 2 Factor so you can login again.  You will then setup your Authenticator like it was new.  Can take days for this to complete.

This topic could be moved to the altcoins section.  The cluster would only be feasible mining cpu altcoins.  Pi's are suitable for controlling some miners for bitcoin but most have them embedded already.

The best thing you can hope for is to run 1 card on this motherboard and it needs to be a gtx 1060 w/out additional pcie requirements.  Then you can use your current setup.

Garages are fine as long as the intake air from a vent isn't right on it.  Even in a cold climate the rig needs proper venting.  1 rig at least a box fan blowing out a vent and vents for incoming without a fan should be fine.  (as well as a circulating fan on the rig itself).  You'd be surprised how much heat is put out with just a few cards.

 If you plan to have it in the basement, noise not heat would be the concern.  Then you can vent the heat upstairs and turn down your thermostat.  I'd choose during the fall to heat my house and earn coin rather than pay electricity for heat and rigs.

On the condensation note:  Inside the garage or basement isn't a concern once you have it run for a day.  It will dehumidify any home!😉

Glad to hear.  Had the same issue before. 

Psu connections to start, network next and make sure your pool info is correct - that would cause a reboot.  You can save the default software then update it from Bitmain.

Hate to recap but only the first gen Asics truly made money for home miners if purchased early.  Every thing since has just been almost breaking even.

Of course!  It's for profit and there's no profit in long term inefficient btc miners.  Gpu's now carry for several years depending on model but that's for another thread.  On average most Bitcoin rigs have about a year or just over to stay profitable from release.
If it weren't for power costs and btc price/difficulty no one would ever need to sell.

Maybe I'm wrong but those cards do not require dummy plugs.  They either work or they dont, not represent a lower hashrate if you don't use.

Today they released the 2FA on my account and all holdings are still there, thank god.  Still would recommend caution trading here. 

Yes, accusations seem to be true.  My last post was deleted off of here a page back.  My account now has 2FA enabled which I didn't do, so now I can't login.

Are you using the image just for Nvidia cards?

PM sent.

Are the XFX cards 8gb as well?  What does "not quite reference" mean please.

So that works for you with Decred?  But are you still trying to mine Sia?  I know my Sia pools require quotations in the config line.

So this site works like a brokerage for other exchanges?

I know I have 4 Compacs and may 10 Block Erupters as well.  I can check tomorrow when I get a chance if interested.  I love stick miners also, they're very satisfying to watch.

Yes, works perfectly for slapping rigs together headless.  No complaints, not even the fee.  Well worth it.

That's not actually very much considering those dual mining last year.
