Whatsminer m21s arrives this sat the 27th of July

[wndsnb]

If you try to split it you would need to put a fuse or breaker on each leg or you're just asking for trouble. Without fuses or breakers, if one cable fails or comes loose the other cable is now taking the full load and could go up in  flames.

Yea def.  that's why I couldn't find anything that would work reliably.  Shame too, I wouldn't mind running these units but no pdu means no buy.  Stupid to plug this into wall outlet running 24/7.  Imagine your dryer running 24/7 essentially, just asking for electrical problems if a storm comes through.

You can go direct to a circuit panel if you can find a proper breaker.  In my case I have 30 amp breakers and only 3 of them , but if I had 20amp  breaker it would be quasi okay.

What would be nice would be finding a pdu with a 20 amp breaker.

I frankly consider the 20s and the m21s units a bit of a safety risk.

To be honest  the s17 pro  2 plug design is light years ahead safety wise.

I googled around and found this  it may work  pretty cheap price

Yea I'm not changing breaker for one miner, plus I have 30 amp outlets which will handle it fine.  Just don't want to direct plug in that.  If the miner can't go on a pdu, it doesn't go for me period.  I wish some pdu's had 20amp breakers, that would solve everything but sadly all mine are 15 amps each bank.  I'm not always around to monitor in person so I just don't trust plugging something like this direct into a wall without a pdu or surge protectors basically.  Even though I have one on my entire panel, still don't feel comfortable with it.  They def. should have done a 2 plug design, would have been way better.

It is why i hesitated to buy these in bulk. I had a chance to get more of these and of the s17 pro.

But I had not tested any. So I did not order a lot of them. If I had  know they run well as they do I would have grabbed 10 and had one sub panel with 20 amp breakers and an isolation transformer.

We are going to add a transformer and do 200-250 more kwatts.
So doing sub panels with 20 Amp circuits are not a biggie.

The transformer would be in the warehouse.  We have two big ones in the building already.

It's too bad the miner prices lately are so inflated and ridiculous it's rarely feasible or worth it.  Hell I remember ordering a bunch of m20 normal ones for about $1300 each about.  Now they want like $1900 for a even later shipment.  Getting out of hand now lol.

We just need a pullback below 6K to quench the craziness and give us another chance to get reasonably priced gear. After that, a bull run to up to the halving would be great....

Down below $9700 ... could be on our way there now.

[fccs]

I don't see it going that low sadly but who knows.  You and 90% of everyone else probably is saying same thing.  We as well as the asic manufactures know the halving is less than a year away and most likely are expecting a big spike sometime next year before then.  Gotta keep that in mind

[judypug1956]

Yeah but selling gear for prices too high for 4 cent power to profit is not the way to go.

Trump tax = death for a usa miner

but even if you are in china the prices are very high.  an in hand m20s 68t is more then 3000 in china.

at 9700 a coin the m20s makes 16 a day power at 4 cents is  3.20 so 12.80 profit

means  3000/12.80 =  235 days  12345Rose#

and a simple price drop  puts you dead.

So the argument  is  pricing is now geared ar 2-4 cent with  most all risk on the miner not the seller.. What  big miner buys in..

We know I got a m20s at 2050   which means the builder turned profit at that price.

I see no price under 3400 for the same gear  that is all profit for the builder.  Risk has been shifted to the miner.  Even a 4 cent guy in china has risk buying at 3400 or even 3000.

does not look good.

We'll hopefully the Trump tax will motivate some American companies to get into the mining asic business. Would be great to have AMD and Nvidia in the game.

[minefarmbuy]

Their products would still likely be made in china.

I think even before the tariff situation many companies were looking for other alternatives, Vietnam for example.

I'm not so sure there's much advantage of building high cost and low complexity items like these in China vs USA. A $300 cellphone is another story ... 10X more complicated and 10X cheaper. 50% of Samsung's chip fab capacity is in Vietnam, and TSMC's is mostly in Taiwan, so the real guts of the miners are probably not originating in China anyway.

All they have to do is ASSEMBLE it outside of china

edit: This m21s sells for 1900

Got mine a few days ago , paid 1500$ for it, it should be here , given the price of bitcoin now and the time you bough yours it seems like we paid the same amount of BTC except you got yours way ahead of me, never really had a miner from whatsminer,  i have been a bitmain fan , but thought I would try something new, will post my reviews when it arrives.

[philipma1957]

nice look forward to seeing if they changed the low power setting.

The issue I got this from my reseller in China not directly from the manufacturer , it is brand new but I am not sure what batch it comes from, so it could very possibly be the exact same batch you got, either way, we will find out pretty soon, i will keep you updated.

[philipma1957]

Mine was delivered in august. high speed was 54-56th    65 watts a th

low speed was 29th it was very quiet at this speed, but it did not save a lot of power  60 watts a th

since miner is at Clifton those numbers are off the top of my head.
