It's the south korea banning of cryptocurrency that's making the market volatile right now:

Is it a good time to buy? Probably the main currencies at least (bitcoin, ethereum, z-cash, etc).

XRP (ripple) is down to $1.49 this morning.. That'd probably be a good one to buy right now. Hopefully everyone dumped TRON before it plunged.

I'm down a good bit over the last week or so. I'm still debating if it's too late to pull profits, or if things are going to turn around and I should start buying.

I have a friend who is getting involved in the medical record side of all of this. From what he had told me it is something that could be seriously beneficial to me in the future.

I would pay a premium for a usable medical history. I stress usable. I see myself going to the doctor and having this information useless to them for atleast five years, optomistically.

So I would pay a premium. Possibly with little benefit. Again a future state thing that could help me. And I believe others. But I would pay. Even insurances could be allowed or required to feed into it.

I don't know. I like new technology though. I'm watching all of this, as a spectator.

Answering this question is the challenge for me. How do you value any cryptocurrency? Otherwise, if you don't know when to buy or when to sell it is just gambling your money.

My take (and I could be wrong) crypto's are on sale right now...lowest prices you will see all year.

But don't gamble what you aren't willing to lose.

Perfect time to buy. All the main ones should go up 30%. I wish I had more money in there so I could buy more.

So what we are seeing today shows that BTC is still inside its rising channel:
http://bit.ly/2r7yPdo

Bitcoin has broken right down to the bottom of the channel on multiple occasions.

I'm hoping you're right. I grabbed another 0.23BTC @$11,800 earlier.

I have some Ether sitting on Binance and was thinking about doubling down on XLM, LINK and maybe some XRP. I'm still on the fence on throwing more at the altcoins though.

TRON (TRX) has dropped 74% in 11 days.

yeah but that was a special case of extreme fraud and ineptitude.

Agreed!

Ooof, I moved all my BTC to XMR yesterday but both are really taking it on the chin - down to $405CAD vs. $520CAD yesterday. Hard to HODL on this rollercoaster!

Left in the open isn't as effective as a cooling housing that is forcing air in/out in specific ways.... because you aren't moving the ambient air or really getting the hot air 'away' when just left open.

You might want to tell these guys about the physics of cooling a crypto mining rig

My 3 little GPUs running at 60% of their max fan speed while hashing at 65MH/s will be just fine.

Doing something stupid at scale... doesn't make it any less stupid.

A real DC uses hot and cool zones with forced air moving in specific directions to work with convection movement to ensure heat is moved out and cool is moved in. And for those who build custom hardware for their DC... like the googles of the world, etc... you build your heat exchangers on the hardware intended for that kind of setup. It's an integrated system.

i keep the door to my office closed. it has two windows, both are slightly open. the rig sits below one of the windows, with its fans sucking air in from outside. the other window has a stand-up fan blowing air out the window. i can control the temperature in my office very precisely just by turning that fan between off/low/med/hi. on hi, it quickly turns frigid in here. when off, it gets pretty hot. the fan is usually on "low".

ExtremePinball how you holding in there buddy?

That's frightening

I believe we are witnessing a "futures" crash. The first futures contracts come due on the 17th. This is market manipulation at its finest.

And yet people still live on the streets in this country, while people get rich playing with pixels. Jesus. Christ.

(Just a general comment, not against you at all. Keep on keepin' on.)

Meanwhile, the idiots like me believed the hype and bought tiny amounts of currency as it was exploding, and now I'm watching this today going "Nope. Nope. Nope." gonna trick me again lol.. I know it's a logical fallacy but I don't give a damn until I at least get my original amount back, haha.

Here is what I read on Reddit to explain further:
On December 10, BTC futures trading went live. The first set of those contracts is set to expire tomorrow, January 17.

For those who don't know, futures contracts are agreements to buy/sell an asset (like BTC) at a specified future date and price. As the price of BTC was ~$15,000 on Dec. 10 , the first BTC futures contracts, which expire tomorrow, were fixed at about that same price. In a simplified form, this means that tomorrow:

the "short" side of those contracts must give the "long" side a BTC (which, if they don't already have, could simply be bought at tomorrow's market price); and
the "long" side of those contracts must pay the "short" side $15,000 in return.
Now imagine you are a large hedge fund evaluating these contracts, and the crypto market as a whole, on Dec. 10. Obviously, making a large bet on either the "long" or "short" side is extremely risky, since the price of BTC when the contracts expire (January 17) could very easily be $50,000 or $500. This makes large bets on either side a bad option for a large institutional investor like yourself.

However, you also know that crypto is still an emerging market with a large amount of new investors and "dumb money." And because you are a large hedge fund, futures contracts opens the door to a third option: use large bets on both sides to manufacture market chaos and make money on the ripple effects with little to no risk. Here is how:

Bet big on the "short" side of the futures contracts on Dec. 10. Let's say you do this for 10,000 BTCs. This means that on January 17 you will owe 10,000 BTCs to the "long" side of those contracts, receiving $15k per ($150,000,000) in return.

Buy an equally large amount of BTC on Dec. 10 at the market price ($15k/BTC). This cancels out your risk/reward for the futures contracts, making you essentially immune to changes in BTC's price while you hold both the contracts and BTCs. This also allows you to accumulate and hold an extremely large portion of the BTC market while taking little if any risk .

Shortly before your futures contracts expire, dump all of your 10,000 BTC on the market at once. Like clockwork, this will trigger stop-losses and panic sells from the consumer BTC market, virtually guaranteeing that the BTC price will continue to dip well below whatever price you just sold those 10,000 BTC for.

Ride that dip you just created to buy back the 10,000 BTC for much less than the price you just sold them for. This is particularly easy, since the funds you need are already liquid and ready to get back in the market.

Use the re-purchased 10,000 BTC for the expiring futures contracts, which get swapped for your initial investment ($15k/BTC). The difference in the price that you sold the 10,000 BTCs to start the dip from the price that you bought the BTCs back during the dip becomes your net profit.

For funds with access to enough capital to move the crypto market, this play should be easy money. It would also explain the series of huge dips (seemingly out of nowhere) that we are dealing with today.

Yes, I noticed that, heh.

I'll be fine because I've only put in about a pee drop worth of money...not even as much as I would spend going to a casino for the afternoon if I were so inclined. But it's looking very unlikely that I'll get my money back out of ETH. The BTC...yeah...there's a good chance just gotta sit a while (and listen).

I’m just hodl’ing. I know it will bounce back in a few days and hopefully at an higher level than before. Not worried but then again I don’t have the rent money tied up either.

I'm in the same boat. Just wait and see what happens. I don't exactly have a lot of money tied up in cryptos so I'm quite happy to see what happens with the bounce back.

2 new available. Veddha 6 GPU mining racks with 5 fans. Plus minimal shipping from IL. Some assembly required. $185 each. These are the same rack as shown in Pezpunks post #1231.

I ordered them from Ebay in china last November and waited 6 weeks for delivery. While waiting, I built two of my own from oak flooring, put them into service and then decided to standardize on 8 GPUs per rack. All my future rigs are using the Veddha 8 GPU rack.

PM if interested. Paypal FnF payments.

This is how I cool my rig. Runs all my GPUs under 50c. Still trying to find a good balance.

My whole rig, monitor, fan everything pulls 850 watts. (890 if monitor is turned on)

GPU 68% power, +200 core, +720 mem, 50% fans @ 3050 Sol/s

I can drop power more, but like seeing sol/s over 3k.

This is the most bat shit craziest thing I have ever seen the modern world come up with!
Only thing I see is pure and utter G R E E D !
Its like a Seinfeld show, it something about NOTHING

still dropping!

Some days you wish there was a closing bell and time for a reset.

I concur. I “awoke” at the end of 2017 and am into crypto now. I can tell you that almost nobody I know does this and even fewer mine which is my next move. We are talking probably less than 1% of Americans trading crypto. 99% still give me the WTF eyes when I talk about it. They don’t care...yet.

Warren Buffet changes his mind about cryptos.

Don't forget China. They are even going after local mining operations. Interesting stuff.

I upvoted becasue that was funny.

Still holding (I might be wrong). I'm still going to stick with my prediction that Bitcoin will be worth more at the end of 2018 then it ever was in 2017 (I might be wrong). A lot of shitcoins are going to vanish in that same timeframe though. Of course new ones will pop up when the market returns.

We make fun of TRON (as we should have) but that a-hole made off with a lot of peoples money (He's rich bitch!)

I'm still HODLing on too. But it's disheartening when you open Blockfolio and see this in the top right corner. I was at -$7,000+ at one point.

It would help instill trust in the USD/BTC conversion process if this didn't occur so regularly.
Very akin to a Bank closing early or ATM being locked out and empty.

It's been an unhealthy obsession how I've been watching the markets. I mean, I don't have anything better to do, really, but watching the candle graphs go up and down all day is kind of exhausting.

amazing bitcoin dropped below 10k.. now its back up to almost 11k, which has made everything else rise. tron was down to almost a nickel again, its up 60%. hope some people in this thread bought some stuff today.

was definitively a few crypto sales on today!

Finally I can stop vomiting, nice to see a sea of green.

Yeah right. F you tron you not fooling me again lol.

What a friggin rollercoaster! Talk about shaking out the loose hands. BTC is currently back above 11k , ETH above 1k and LTC is nearing $200.

Downsides:
I barely blinked during this whole thing...which is a little disconcerting.
If it keeps crashing and recovering (in hours/days no less) how will we ever know if it's really crashing for good?

Is it bad that I have skin in the game but I still find the insane volatility entertaining?
I guess I'm treating it like poker chips. It wasn't money anymore after I "bought in". I shoved my chips in on BTC, ETH & LTC and I'm just waiting for the hand to play out. Either win a big pot or lose my chips. Only time will tell.

I bought a small chunk of bitcoin for the first time at $9900.

Way to hit the bottom...not that you knew that at the time

Haha yep

Classic pump and dump. Hanging on every move it makes, fear and greed, up and down.

Big flush rush to the exits is coming

Like all those buys except the xrp.

Haha yep. Stock market will correct. Just a matter of time.

I know you understand the differences between it and the Crypto crap table Extreme!

Every dummy with a quarter in his pocket thinks he’s a crypto expert and will make a fortune

My daughter’s friends say they are “heavily invested” in crypto. So no worries
