so 13% for eBay and 3% for Paypal?
Shit, good thing I moved to selling crap on CL years ago. I prefer the in-person style of that better anyways!
10% for ebay, 3% for paypal. It's fucking CRAZY. Sell a block erupter for $100: receive $87 Sell a mining rig for $1000: receive $870 Obvious outcome: sellers add 13% to the sale price. |

I can't believe people still do this despite all the scammers that have been charging back and using stolen credit cards to buy them. Good luck with that.
I assume that is all through Paypal? I've sold 3 mining rigs (pi, hub, 5 erupters) and 5 single erupters on ebay, no chargebacks. I think the frequency of chargebacks is blown out of proportion. Much more common is deadbeat bidders, which waste your time. There are a ton of better reasons to not use ebay/paypal: 13% fees, holding your cash for 3 weeks, etc. |

Loving how the ROI timeframe on these shares is now as long as bitcoin is old
-Buy share for BTC4 -??? -Sell share for BTC4 ROI = anywhere from 2 seconds to infinity Oh, wait, you must have meant "the amount of time it will take these shares to collect their face value in dividends". For a second there, I thought you were talking about something else. |

ill get 2 and move up our progress toward 24...Id get at least one more too if it ends up making the difference between 23 and 24. Really, anyone who ordered 2 at $15 should be up for a 3rd one if it gets us to 24, because then its free!
I cant send BTC until I get home from work in 5 hours though, not sure what time you wanted this to close, but lets keep it open till 24, eh?
I'll update the OP when you confirm!  I'm leaving for vacation on July 20, so I'll keep this group buy open for at least another week or so. Didn't get a chance to print anything today, as the blank shirts were stuck on the wrong side of the ferry (I live on an island). Looking good for tomorrow |

Proof of concept code for this exploit (yes, exploit) here: https://bitcointalk.org/index.php?topic=251051.0Incidentally, if someone wanted to clean out a bunch of accounts, they might do the following: -create a dummy account with a payload-containing URL in its signature or on its profile page -poll the forum for commonly-used words and phrases -make nonsensical posts using the phrase list, in the hopes of enticing users to click the URL -clean out any users foolish enough to click the URL while logged in to an unpatched site |

blockchain.info's SMS verification is similar to what you're describing. The login page sends you a one-time code via SMS that you must enter into the browser, along with username and password.
For a trivial amount of effort, you could extend this to any sensitive action: sell, transfer, etc. No yubikey or even smartphone required, just a phone that can receive SMS. The security-minded could purchase a cheap prepaid mobile phone for this purpose, and keep it in a secure location.
I'm not sure of the cost related to sending out that many SMS messages, but that's not an insurmountable problem.

Either way, I imagine the price of 1btc each, even with the recent USD/BTC events, is far above cost. We can afford to drop the price more, and sell more... at a profit.
Marginal costs are something like $0.8 per chip. Obviously there are other costs involved, but you're correct in that the price can be dropped massively. So ASIC can be quiet cheap when you compare them per individual chip price, but it's a big start up cost for the designer. FPGA's are more expensive individually, but you can do more with them, and on a small scale the cost is easier to pass on without hurting their accounts.
Thanks. Yes, basically the more ASICs are produced, the lower the cost per chip becomes. I'd estimate the Block Erupter chips (just the chip) will only be $5-15 a piece ...
In fact, the margin cost per chip is less than $0.8 a piece, that is hopefully $0.8 per GH/s. Of course, if we consider the cost of heat sinks, fans, PCBs, power supplies, and the disperse of the initial NRE cost into each GH/s, it will be significantly higher, but still within a single digit dollars per GH/s. As it stands now, at the very least it looks like that will be roughly 10MHs:1$ ...
If only considering the whole production cost, it is easy to achieve more than 100MH/s : 1$. The actual market price is another story of course. |
