Pro tip: Not now.

Explanation: buy low, sell high, not the other way around. If you bought higher than today, you do nothing but wait, no matter how long the wait. Else you lose money, period.

This is exactly it. Dropping further and further before the halving? Heh, that would only trigger a crazy pump that would need to correct afterwards. But no, the pressure from the bulls is there, halving is coming. After, yes, bear cycle probably.

The bitcoin price in fiat does not affect Bitcoin, therefore you cannot consider it an attack. An actual attack would be, for example spamming the network with garbage zero blocks like they tried early 2018. Or the infamous 51% attack.

Attempting to manipulate the price in the market, is just some people wanting to make profit with their trading. That doesn't affect Bitcoin which remains working as intended.

Bitcoin does not oppress anyone, because its use is optional, not mandated by the State. If some entities feel they will start losing power, there is nothing they can't do about it. Again, manipulating the price does not affect Bitcoin at all.

If some whale found that you could trigger a "panic sale" of fools by doing a mere transfer to an exchange, i guess good for him/her. The market is full of immature traders, and this could be one way to weed them out, by making them lose and quit. Natural selection i guess...

This is a chance for many people to buy cheap, enjoy while you can.

I really can not understand how people are still using Windows to store their crypto. Missing security features should be enough to switch to Linux.
And additionally, you can always upgrade for free..

There you go, fixed it.

That's easy, use a secure OS, and manually input your own trusted DNS resolvers.

I would recommend the use of an OS Like Linux, and dnscrypt-proxy as dns cache, which happens to use the newfangled secured DNS methods that third parties (such as your pesky ISP) can't sniff on to determine what sites you are resolving all the time and data mine you or worse.

Sure, in theory you could tell your windows to manually use cloudflare's or google's, but any random malware of the day can wreak havok at any moment without you even noticing. Worse they would resolve a legit site into phishing site... Which is why manually inputting an address in a browser isn't as safe as some think it is...

While less common, hijacking can also occur upstream, at your ISP level, or above that, sometimes by the State...

Dnscrypt-proxy is great because it self updates a list of secure DNS resolvers that use your favorite secured methods of communication, and is always using the one with the lowest latency. It also caches, so its great for LAN setups...

Hmm, my country has a single ATM listed, and its at a border city, apparently its inside a traveling agency...

Operating an ATM in the country with the world's worst inflation, sounds like fun. Here you need twice our fiat to buy 1 satoshi. Largest banknote is 50k, so imagine it like 25k satoshis. That's about 2 USD. I guess an ATM with only 2 and 1 USD banknotes only is doable, but still... The inflation is measured in million percent yearly, the purchasing power of the banknotes changes every day.

I still think a single customer transaction would fill (or empty) the safe-box, and he/she would probably remain short of funds anyway.

Nope, true adoption is not putting an ATM at your shop, is having your shop setup a wallet and integrate it with your accounting, or at least set up your own processor such as btcpay.

The ATMs are an unnecessary middleman that only over complicates things.

Exactly, or take the chance to buy, as these chances don't come too often. What if, after the halving the price parks at, say, 12k? (after maybe a brief peak at 20k?).

Price will correct itself eventually, if it was too high, it will lower, it if was too low, it will go up. The fluctuations occur naturally as some actors buy or sell, which is perfectly fine. A flat line is a sign of danger, a vigorous fluctuating line means its alive and free.

After the downs come the ups, and after the ups comes the down. But on the long term, you see the price is climbing, as it should be given its deflationary design. In this long term line, isn't actually a line but a logarithmic curve, that it starts very steep up, nearly vertical, but is slowing overtime gradually becoming horizontal, meaning, price increase should be slowing down as time passes in the long run, with the highest rises in the very beginning. But remember it will never go flat, because fiat is devalued intentionally, while Bitcoin is not. Therefore bitcoin keeps its purchasing power, and slightly increases it over time, while the fiat coins are being intentionally devalued by governments over outdated economy dogmas (fear of deflation).

These two walls... I'm pretty sure some of the hot air will run circles which in turn is like creating pressure against the exhaust of the miners.

Unless your inner wall had no vents and only fans...

How is the humidity over there?

Unfortunately i don't know of any Asic miner with software shutdown, all they can do is restart, and if you go the Braiins OS firmware route, you could in theory reduce its consumption significantly but not completely turn it off. If it is of any help, think that each miner could change from pulling 1400w into 360w with that trick, depending on how many you have, it might be easier to do it this way.

All you need is to do is run a script in the miner itself to poll the power condition, and act upon it. In your case i would have two cgminer.conf files ready, one for normal condition, and another for low power condition, and switch accordingly. The script would just run off cron periodically as often as you want (just don't run it every second, please). Software changing the speed is rather simple and painless, it only restarts cgminer.

The only other alternative is as you said, turn on and off the PDUs. If you go that way, try to use different delays for each PDU, avoid having all of them go on and off at the same time...

Indeed. The hashrate is completely dependant on the crypto algorithm being mined, and each algo produce completely different results in speed, some you see measured in hash per second, while others in kilo or mega hash per second.

Currently CPU mining is unprofitable or nearly useless. Perhaps with the likes of monero you could earn 1¢ or something in a month. GPU mining is a tiny little bit better but generally useless at this point in time.

It is absolutely worthless for Bitcoin, and you posted this message in the wrong section, and should move it into Mining (Altcoins). This area is for discussion about Bitcoin, this is a Bitcoin forum and anything not bitcoin goes into Altcoin or its sub forums.

There is no loss until you sell. Those who faithfully keep their coins and wait for the storm to pass, will eventually overcome it. Panic only makes people react impulsively and mistakenly. You need to act cold, which is why you were supposed to invest something you didn't mind "losing" in the first place, so that you become unaffected by these normal price fluctuations. Just wait it out, or take the chance to buy cheap coins while they last.

End of the year baby bull run? Better prepare for the halving bull run...

Why would anyone be surprised after a decade of price fluctuations like these?

In the long run, its been climbing fine. The year started at like 3k~4k, its still quite good.

Meh, just wait it out. And if you have some excess fiat lying around, its your chance to buy cheap. Panic sell will only lead you to loses, the price will find its natural place, and if it doesn't correction ensues.

Hashrate lowers probably as it becomes unprofitable in certain territories, so those miners simply stop mining. Since the diff is adjusted every 2016 blocks, it may take a while to adjust when sudden changes in hashrate occurs.

Of course panic selling leads to losses, people doing that simply do not have the discipline required to enter the game in the first place.

If anything, cheaper price is a chance for many to buy, hurry while it lasts...

Lol 6" is barely acceptable for a single S9, and the S17 is basically twice that... I think you need to move about 500 CFM, perhaps you need a second duct unless you can do it with some inline fan. And of course, fresh air needs to be able to get in...

Correction, their miners are made to run at 230v @50Hz, this is what they will test their PSUs first and foremost, because, that's the mains in China. The other voltages are more or less lab test conditions. Of course most of those PSUs work happily with a bit less (such as 208v from two 120v phases) or 240v as you get in America for dryer/AC circuits at home or such.

But this also means, slight deviations will get into the danger zone faster, such as going 250v peak that in China would have been a 240v peak...

OP should indeed test each single board separately, and swap data and power cables, the usual procedure. And remember to test them for an hour or so hashing.

And yes, S9s are not meant to run at 110v... maybe if you stick to use two boards only (remove the middle one), like the R4 used to.


This is theoretically not allowed by most electric codes, no "110v" circuit (actually 120, some places 115) should go above 1500w ever. You are over stressing the circuit and the PSU. But of course technically the input the hashboards want is 12v and some hundred amps (i forgot).

Perhaps using two PSUs from different phases would be better, but then again if you can do that you can also do the 208v "magic" trick...

There is no need for this, most pools will auto adjust the difficulty to what you can actually deliver, be it hashrate or bandwidth. Forcing it usually leads to a worse (suboptimal) situation, let the pool do it for you.

You can use 4g here (sometimes, lol) and when it works, it goes really fast. But they cap it to like 1g of data per month so you can empty it in like 1 day watching youtube. Then it stops entirely. A couple of the companies (there are just 3) charge you per byte after that. The third is State owned and is a weird mystery. It would be too complicated to explain, you can't even tell what data plan you have, and new customers are not offered data plans at all (everything is metered by the byte, and expensive).

Most likely there is no 4g coverage where that setup is. In many not so well developed countries, mobile data coverage is... random. Maybe no data but phone, maybe data but the slower one, maybe 4g but after an hour it switches to the slower one, or leaves you without data until you reset it...

And here sometimes you can even get 4g link but no internet, because they have problems upstream as well...

While Bitcoin will be known in the future as more solid (price) and better valued than gold, linguistically i think it has no chance. "Bitcoinish" is too convoluted a word, hard to pronounce compared to gold and golden.

There are some other metals better than gold (in price/scarcity) out there, but people keep coming back to use the gold word.

And if you say "Bitcoin opportunity", people will be expecting to at least earn bitcoin from it.

There is a genuine concern that in fact quantum computing renders all classical cryptography obsolete. This has been a theory for many years, but of course even the computers themselves had been theoretical (and some people have even made programs for these theoretical computers).

However one thing is truth is that this is slowly but steadily advancing, and we shouldn't go back to sleep. Even if its not today or not particularly that Google computer, you can be assured that the first people who are able to get one big enough to do harm, will keep it quiet (or ordered to remain quiet), America DOES have gag orders and national security, so an American company is the last source of reliable information on these matters to be made public in time.

It will go something like this, perhaps in Japan, or i don't know what other country, something "better" than these Google/IBM computers come, and them other countries join the race, while "still not quite there" as you are right now writing here.

And from America, silence. Or perhaps a few more announcements, then silence.

You won't know it, but the NSA is in my bet one of the first institutions to have one operating, provided by one of those American corporations sure, but in their control. Perhaps this is but a race to the bid, the State can be such a juicy client, even if it means going silent when they order it.

And remember when this time comes, it would be too late for "discussion". Discussion should be done now, and solutions implemented.  There have been proposed solutions to mitigate quantum computing in this transitional phase, and they should be implemented while we have the time to do so, not when its too late to act...

Decades later quantum computing will reach the masses, and the playing field will be level again (with quantum cryptography algorithms). But in the transition, it will not be this simple, in fact, quite asymmetric. Do you believe in those institutions that will own and operate the first ones? Its not the Americans alone, rest for sure that whatever America makes, China will get it, and Russia, Israel, at some point Europe, etc.

Yes of course they are going to use it to unscramble "evil terrorist" stuff first, or at least that will be the excuse. But in the way, "other" stuff will be revealed, without the affected parties knowing...

Scandal-drama again. What was the Watergate scandal again? No one remembers, and yet a president left office for that in the middle of the "cold" war... Will you wait for the next Snowden decades later to leak it?

Bitcoin is not in danger, but don't wait a couple of decades to address these issues...

That's not volatility, that's freedom. And that's not a crash, but a miserable 5% price reduction.

I will hit you with the concept as many times as you abuse the word crash:


Your expectation with these "panic scare" words? Nothing. The people here know better, you waste your time.

Has bitcoin price fallen to 1k? No? Then its not a crash. Cheaper bitcoin is an opportunity for others to invest...
