Unfortunately, their warranty states this for years. You send it in and they try to repair. REPAIR, not replace parts. If deemed not repairable it will be scrapped. Pretty bad policy, but they can get away with it as…

I believe it is not tampering. Bitmain's warranty (a read the fine prints some time ago) works this way: You send it in and they try to repair it. BUT: if can't be repaired by their methods/policy then they WON'T…

Volume is a myth/scam I believe. Current unit prices with current difficulty don't make financial sense even if you get sub 5c power and 1000+ units. Even volume prices are too high to make a ROI. Well expected ROI as…

Indeed, but to reach that efficiency the hashrate goes down a lot (also need some luck as not all units can reach even close). The 100TH unit will do 80 or 70TH hence the price needs to lower again.

I think there is a huge difference between profit (eg. monthly for a while) and ROI Like today BTC is ~22K and with current difficulty an S19J PRO 100TH will make you about $180 worth of bitcoins (-costs!). Minus your…

I doubt that any banks will understand. They will run away as you mention bitcoin, especially mining. Even if they do I don't think they will give 10K+ low interest loans without collateral. I think your best bet would…

It could very well be 44c depending on the plan and place you are. Still it is a horrible price, you will need 1/10 of that to make mining viable.

44c/kWh is that a typo? I mean that is horribly expensive even by EU prices. Doing anything at that rate is pretty much out of the question IMHO.

Are you also sure that the TOTAL cost is 4.7c not just the power (add transmission, taxes, demand, decommissioning, etc.)? I mean when you divide the final amount of the bill with used kWh you got the 4.7c?

Biowaste are very effective in mining. There are several ways to generate them, I see it only as a waste. If the energy is generated by mining, then by mining the miners are not very good. The people are very lazy to…

The bill that will be introduced into the Missouri Legislature is also very simple, but one thing I'm sure he won't do is to get to the stage of the law enforcement on his behalf and to keep him out of it, so his bill…

As precedent for other states maybe, but in the US the federal law is the bigger problem and this is state level. (see weed federal vs local laws)

7$c (assuming you meant USD cent) is not that cheap, but not that bad either. I did read somewhere on Bitmain's site that albeit plug on/off is ok, but not advisable to do so a lot. So for the very same issue we wrote a…

Not all people are that much interested in mining ASICs like Intel. They're going to want a lot more for themselves. Intel has already started to offer their products and at least part of the company already has an…

There are a lot of people who don't know about this, but I'm sure you can understand what you're trying to do. First of all, not a developer. Second, you need to be a developer. Third, you need to be a developer. And…

Depends on the conditions. High humidity (but still below specs!) will ruin the temp sensor on the farthest board in a year or two. Applying protection on the temp chips (nail polish type) probably solves this. I guess…

The main difference that you can gain much much more than just the block reward with the long term attack. Imagine if you hidden mine your longer chain for two weeks. Under that two weeks you can send your real bitcoin…

Of course I can. I can have 1 Bitcoin and I definitely have unlimited addresses. I can send this any time to any addresses in any amount, hence I am able to create an unlimited number of valid transactions. The only…

EU VAT you can usually claim back (or not pay) as a EU VAT registered company. Not that it helps miners with the power rates all over the EU...

It is close, but the attacker could also get more hashrate with new machines (I mean now we are talking about single digit %). So the already disappeared hashrate maybe less than the current (possible) attacking hash…
