Crypto currency mining

[ainarssems]

Anybody else getting coupons from Bitmain? I have had $125 coupon for couple of months now and was unable to use it for A3 order but it let's me use it now for L3+ order. Last night they sent me another 3x $100 coupons and then 3 minutes later 1x $200. I guess miners are not shifting as well as they would like to so they are giving away coupons to encourage people buying.

Same here; one for $200 and three for $100. I also seem to have an older one for $125, all with an expiry date in June. I had one for my original S9 too apparently (for $150) but I think it expired before I could use it.

I wonder if you can combine them? Might be worth ordering another miner (just to sell it) if you can.

No cannot combine them, looks like you can use 1 per miner. I only tried it for L3+, if I add 1 to order I can use 1 coupon, if I add 3 I can use 3 coupons. If I only buy PSU's or router coupons cannot be used. Don't now if you can use them for all miners, I was only trying it on L3+, but a while when I was buying A3 it did not let me use coupon for that. I think for now I will only order 1x L3+ using $200 coupon, still plenty of time till June to use others.

Since the RX580s won't play nice with the Vegas I decided to make them do something useful instead: an Ethereum-mining cat bedroom warmer that makes 4mBTC a day







This sits on the worktop in the utility room to keep the cats warm overnight

Sorry to drag this back to the Monero mining question, I've been thinking that as I work away a lot I have free electricity and free internet when I am onsite. looking at the monero mining via their official wallet, I've set the laptop to 4 CPU threads and I am apparently mining at 42-65, what would I expect to achieve doing that? I am just wondering if its worth doing with this or something else as its sitting there and doesn't cost me anything.

I ask again because I have 3 machines I can do this with and no outlay costs on internet or electricity, so potentially thats mining between 120-180

There are usually calculators on the pools to work out returns for hash rate. 60H/s would get you about 7p a day for either Monero or Electronuem. I'd be inclined to do the latter since at least you'd get whole coins (1.5 a day at 5p each), whereas with Monero you're about 0.1 a year.

etn.spacepools.org is good for Electroneum - low fees and a payout at 10 ETN so you'd probably get a payout every 2-3 days if you had all four machines running.

Thanks for the links, yeah, its not worth it, I'll can pull in more trading on an altcoin with a couple a hundred, I'll turn it off ha ha

haha. Neat.

What's holding the graphics cards in place, the PCIe riser PCBs?

And what happens when kitty curls up on top of said heater?

[MikkiJayne]

The riser boards and the PCIe power cables for now I'm going to make a bracket to hold the front of the cards to the board, but its too cold in the workshop for making anything at the moment!

The kittehs seem fairly uninterested in it tbh. They investigated it for a few minutes when I put it in there and made sure the fans all had some fluff in them, then lost interest They have a duvet on top of the boiler on the other side of the room so sleep on that. Its raised the temperature in there from 17 to 19 overnight so its doing its job

Neat. Looks a nice little set-up. I'd be tempted to shroud and add a filter though as cats create all sorts of dust and fluff which is less than good computers. Even a box over the top with some foam type stuff covering the vents!
