It's just another way to invest. Having a diverse portfolio is a good idea, especially if you're looking ahead and seeing less and less time to earn and more and more time you need to budget somehow. It's like bank stock. It'll vary, but it's more likely to remain stable in times of crisis.

It depends. If you have the capital up front, shutting off your miner when it starts not covering electricity and just buying the amount of electrical costs in the coin is the most profitable way. If you don't have it up front and FIRMLY believe the coin will bounce back, leaving your miner on does make sense, as long as you can pay the electric bill eventually (think of it like how credit functions).

Also if you have use for the heat, I use an S5 in my bedroom when the weather shifts. Even though it hasn't been profitable since January, it heats the room and earns back a decent amount of what it costs to run. I have electric heating in my house, so technically in winter it's profitable for me to run unprofitable mining gear as I'd be spending that money on electricity anyway.

Never use pin splitters. If you switch to 220, you can add more cables if you want, but splitting limits you to the max output of each cable, not the overall psu. And yeah, you're right, I forgot there are only 10 cables. You'd have to add more.

It depends which/when you bought. Bitmain's current APW listing says 1000 @ 110. All of mine were rated 1200W, I was just being conservative in the examples.

Mine peaks hashrate-wise at 718MHz, and draws around 350-360 according to my kill-o-watt. Are you on 110-130v or 220-250?

Even at 420, you can safely run two on one APW3++ (as long as you have enough room on the line). 3 is a risk, but two should still come in under the max (unless you're on 220, in which case you could really run 4 if you add more cables).

EDIT--to run three you also would have to add two cables, my bad.

The mini draws like 350W overclocked. You can likely run three of them on one APW3++ (though it's rated for only 1000W @110, I've never had a problem going over with any of mine--not suggesting others do it, just saying).

The A3, T9, and the S9 are the only Bitmain miners I know of that this is a concern for. I don't have an S9 or T9, but for the A3 the bitmain standard PSU worked fine on 110 in tests, but I didn't want to risk it and powered one of the cards with an old PSU pulled from a dead tower.

I have one taped on, using metal tape and covering the additional vent holes. It's for ducting purposes. Once I finish my cabinet, though, I will likely remove it as I think it ran a couple degrees cooler with the open front.

A 20amp 110v line provides 220W. by the 80% rule, that means a constant draw of 1.76kW is perfectly acceptable, you just need it to be a dedicated line. (this is an example; most of the single phase lines in my house tend towards 120v, so their ceiling is higher).

I'm not saying 220-250v isn't preferable, it is, for numerous reasons (more efficient as well), just saying I ran all my miners, including my A3, on 110v lines until I set up my subpanel. You just have to make sure you're not putting high draw gear on busy circuits and not hitting the max for the house as a whole. But again, if you're going to add lines anyway, you might as well put in 220v ones.

This thread is like an Amazon product listing--around 15% actual people.

Also SIA has infinite volume (there is no coin cap), so it is completely based on potential usability, not scarcity.

That's the market, not the network. Actual earned ETH per day hasn't dropped very much because the network was already huge and the E3 is no more efficient than midline gpus. ETH has dropped significantly; if you're not cashing out daily, it makes little difference unless the market doesn't recover.

Meh, 1050s still turn a slight profit. I say add on, not replace.

Unless you're shorting...

If you haven't sold, you've lost prospective value, not money. You have only lost money when you sell at a lower price than you bought.

Or use an OS like EthOS that has those settings as part of the main settings.

On the plus side, the ethash network was already so crowded that you're only losing mining time, not opportunity like with the new release of any other miner...

Not at all, pretty much all Bitmain miners are usable at home without any electrical mods (provided your house doesn't have pre-60s wiring still); any 20amp circuit will easily suffice, and most of them run fine on a 15amp line. That said, ALL miners are more efficient on a 220v line, and the A3 and S9 both require their own dedicated lines (I assume the Z9 biggie does as well)...

For sale? Probably. For use? It's the same hashrate/power consumption per chip, the mini will continue to be profitable at the same ratio as the bigger guys, just less on a day to day level.

/\ This. I wish 2/3 of my ASICs still earned double the electricity.

I'm not complaining about the risk or the nature of the coin, I'm complaining about the faulty hardware and the extreme loss of mining time as a result of it.
