To the OP ... Im hoping it will be like that after this bubble, but for some reason .. I think it will be more like the first bubble pop ... much more steady decline, to stay low for a while ... then everyone will get interested in it again at some point =)
1342  Economy / Speculation / Re: We are trending back up! on: December 17, 2013, 03:50:10 PM
I think the overall trend is still downwards... unfortunately =(
These are just attempts that appear to be inspiring noone ... grr

Why the "Totally untraceable" comment? What's the context for that?

Maybe by that point in time they got something like zerocoin fully integrated into the bitcoin blockchain =P
1344  Bitcoin / Bitcoin Discussion / Re: Bitcoin mentioned on: December 17, 2013, 07:24:13 AM
whats intresting is ... early on in the episode .. it was mentioned by the female cop that "victim paid a fine of 5 grand" to stay alive...
Ive not seen any other episodes of this show, therefore dont know if theres a standard currency designation...
But, that "5grand" comment is really close to 4999btc ... as in  , I wonder if this show is painting a picture of the future where "bitcoin" is very widespread.

haha, watching episode now... ah this scene is cool =) nice reference to bitcoin hehe!
1346  Bitcoin / Bitcoin Discussion / Re: Bitcoin mentioned on: December 17, 2013, 04:42:30 AM
Bitcoin was just mentioned on the TV show Almost Human. They just mentioned it in the course of the show progression.
What episode? Ill watch it =)

can someone tell me which parts of the VRM are most important to cool w/ little heatsinks?
It's best to just add heatsinks to the back of the board.  However, the parts you are cooling are the black plastic transistors between the large aluminum cylinders (the filter capacitors) and the large black cubes of metal (the inductors). 

The reason the back is better to cool than the parts directly is that the parts are mounted with a metal pad in the middle that is designed to conduct the heat into the board.  On the other hand, the top of the part is plastic and does not conduct heat as well.  Thus, cooling the back of the board is best.  Also, when you add heatsinks on the top of the parts, you risk shorting out some of the other small capacitors near the devices you are cooling.

To repeat: It is best to heatsink and cool the back of the board under the VRM, and NOT heatsink any of the individual parts.
can you take a pic of what area on the back to add heatsinks to?
The copper around the fets is pretty efficient at transmitting heat, so using a bigger heatsink interface is always better than a small one since the thermal resistance of the solder mask and whatever adhesive you use is actually quite high. As a bonus, there's a couple areas that you can use to help cool the inductors if your HS is big enough to cover them.



Awesome, thanks for the pic, which heatsinks would well for those areas? links to any would be awesome =)

This is the stable price. Buy on panics and bad news.

The only reason to ever sell is if Bitcoin itself is broke.

And Bitcoin will not break.
I have to agree people seem very nervous this whole week and the price could go either way but we are close to the bottom. Even today's FUD didn't take it below 700.

what was "todays fud" ... the whole btcchina possibly charging fees now? or something else I missed?
1349  Economy / Speculation / Re: It's time to buy, not to sell on: December 16, 2013, 03:51:17 PM
Wow... every time I buy BTC the prices goes DOWN the next day.


Bought in for the first time at $670..... price went down to $550 the next day

Bought some 2 weeks ago at $770..... went down the next day to sub $500s

Bought some yesterday for $880...... goes down today at $750

Bought LTC for the first time yesterday for $31...... now it's around $28... Fuck


I mean I'm not scared (yet) and I'm sure it will all rise... but damn, I seem to bring bad luck. Could have saved a lot of money if I only waited a day.

I got the same damn luck, which is why I dont trade =P

What is the absolute best cooler for under $40?

This one works extremely well if you get longer screws to replace the standard ones for the mounting, that way you can install the backplate rightside up and it puts decent even pressure on backside of the board...giving you more even pressure across all the asic chips against the heatsink.

I'll take that 6950 for $110 shipped at current coinbase price. I'll also do $100 plus shipping if you ship with via flate rate.

have had higher offers..
1354  Economy / Computer hardware / Re: [OPEN] 200 gh/s "Sunzi Miner"(Rack Mountable)- 6.6 BTC on: December 12, 2013, 06:37:03 PM

Do note, this doesnt account for unnannounced products coming later next year and hashrate the year after that... expect more so adjust the curve accordingly ... and in a couple years another block reward halving is coming. So... many unknowns past current announced hashrate projection. So, I suspect the next 6 months are reflected well in this calc, but beyond that its a crapshoot.
1355  Economy / Computer hardware / Re: [OPEN] 200 gh/s "Sunzi Miner"(Rack Mountable)- 6.6 BTC on: December 12, 2013, 06:06:36 PM
Expecting hashrate to quickly triple or even more in coming months, but have a reasonable shelf after that... , I think this is pretty close:

As CrazyGuy pointed out the usd/btc ratio is completely irrelevant to purchasing gear with BTC:



I dont really pay attention to the USD / btc price ratio... I just make sure the price per btc & the USD I enter ... equals the amount of BTC Im paying, so I pick easy numbers like $1000/btc  ... that way makes entering 6.6btc easy, cuz then its just $6600 =)    ...
The only time I would pay attention to the btc price is if Im buying something in fiat.
ha, I guess the same thing is achieved when u put price @ 1$ =P .. didnt even think of that before... .. its all the same to me anyways =)

ha, I didnt previously realize the btc price / jump increase of 1% was affecting ROI window.... bleh, now I do...shit now it looks even uglier when u put "no change" =P
1357  Economy / Computer hardware / Re: [OPEN] 200 gh/s "Sunzi Miner"(Rack Mountable)- 6.6 BTC on: December 12, 2013, 03:54:39 PM

Yeah, because 30% increase infinitely can only be sustained so long, at some point there will be a "shelf" for a while. And while it may seem like a "massive" amount of hashrate... each 30% increase the required hashrate increase is a substantially larger amount of hashrate required to meet 30%
In other words, in time 1TH/2TH machines wont even put a dent in diff...

This is another way to look at it ..

That's prob a bit more accurate than mining.genesisblock, which assumes never ending exponential growth. I'm still not sure we'll be adding a billion difficulty per month per jump by May but I'd say that's a worst case. In that event, 6 months break even is nothing to scoff at.

Here's a link for some of you folks looking for more traditional investments. Wink "Zions Direct" is offering a 1% 6 month CD with $10k minimum deposit.

http://www.bankrate.com/funnel/cd-investments/cd-investment-results.aspx?ic_id=CDI_compare_rates_module:cd.aspx:14&local=false&prods=14



hehe nice one ... but traditional investment margins dont exactly apply to bitcoin mining ...
Diff will definitely be near what you stated, if not way before then, given that cointerra has a working prototype now and hashfast is right around the corner.. diff will skyrocket soon enough.
Im willin to bet u and/or who ur selling these for are getting all the profit you can now and reinvisting to up and coming hardware. Im just sayin it would be nice to see a more fair price tag on these.
I might be willin to do like 5btc... =P
But, Im sure there will be others sucking them up at the prices you are wanting.
1359  Economy / Computer hardware / Re: [OPEN] 200 gh/s "Sunzi Miner"(Rack Mountable)- 6.6 BTC on: December 12, 2013, 06:03:21 AM
man, Id love to grab another sunzi but given the latest diff increase and a week of previous diff, made all the difference in the world between a fair pricepoint original 6.9btc and the now ripoff price of 6.6btc....
Id offer 4btc for a sunzi...

Come on now General, I know you didn't make 2.9 BTC in the last week. Now drop and give me 50.

In all seriousness, this is still a great deal. I wish I bought a pre-order Jupiter a few months ago and I wish I bought a few thousand bitcoins when they were worth a few pennies. You can't invest in the past, but you can still invest in the future.

yeah I probably didnt, that was counting my other ASICs but.... this was simply an offer =) meeting in the middle is fair.
Heres a diff projection which I used based on being able to guestimat a shelf... and I can tell you 6.9btc last week including before the holiday was very fair. 6.6btc 10days later after a 25% diff increase ... is not remotely close to fair. Thats a 5% decrease in price on something that became 25% less valueable =P

Heres a hopefull projection on it:
http://btcinvest.net/en/bitcoin-mining-profit-calculator.php?diff=908350862.43702&dcosts=6600&diff_mincrease=30&blpbtc=25&dhsmhs=200000&diff_mincreasedecrease=5&btcusd=1000&dpowcon=0&btcusd_mincrease=1&pcost=0.11&calcweeks=32&dleadtime=0&action=calc#

6.9btc last week didnt look nearly as bad ...(first miner purchase) ... w/ same settings.

of course, whats sad is this centralized ponzi scheme made up by JPMchase is exactly what most people nowadays blindly trust.... therefore it has a high chance to succeed =(
