1  Bitcoin / Armory / USB key security. on: June 12, 2016, 05:04:25 PM
Hi Guys.

With cold storage/airgaps, this seems like the only real attack vector beside physical of course.

Does anyone have any best practice advice on how not to leak private keys, through signing via a usb device. 

Would this be something that eventual Trezor support could help with?  I suspect not unless you could set up multisig with one part on the Trezor device?
2  Bitcoin / Armory / What if a watching only wallet gets compromised.... on: June 05, 2016, 12:41:18 PM
..... are you vulnerable to someone brute forcing the password encryption on the watching only wallet.dat file (if that is a thing).  Or is that not sufficient to steal funds?

Dear Bitcointalkers

We would very much like your feedback on the V1.0 Beta release of our website  BTCTransit


We have built this site because we want to help support what we consider to be one off the obvious Bitcoin “killer apps” which is international currency exchange, be it for remittance or international payments.

Simply select a source and destination currency with a specified unit amount and see the real-time cost (red arrow) or return (green arrow) for sending currency through the international exchange network.

There are plenty of additional features we are working on to improve the accuracy of real-world costs and to enhance user searches and filters, so watch this space.

We would love to hear what you think.
4  Bitcoin / Development & Technical Discussion / Is there any obvious reason not to cut the block confirmation time? on: March 10, 2014, 04:21:24 PM
Lots of infrastructure is going to get build (is being built) that in time will make payments pretty instantaneous.  But until they become ubiquitous, what are the downsides to reducing the block confirmation time and block issuance rate to say 2.5 coins every minute?  I understand this might be no more secure than a well propagated message today but it might help in terms of perception?
5  Bitcoin / Armory / Vista 32bit for offline wallet? on: November 21, 2013, 08:04:10 PM
Any good guys, or should I stick to 64bit for cold storage with windows OS?

New beta release working great for online wallet, 64 bit Windows 7 machine (4gb ram)?
6  Bitcoin / Press / 2013-11-09 Maxkeiser.com: Shopify Integrates Bitcoin for its 70,00+ e-commerce.. on: November 09, 2013, 10:50:35 AM
don't  think this has hit google news yet

http://www.maxkeiser.com/2013/11/shopify-is-now-one-of-the-biggest-players-in-bitcoin/

On December 12, 2010 Shopify secured the acquisition of $7 million in Series A funding, planning on using the proceeds towards product development, international expansion, technology, and infrastructure and developer tools.  Then, on October 17, 2011, Shopify secured the acquisition of $15 million in Series B funding, planning at that time to hire more staff, consider acquisitions, and attract app developers to create plug-ins for the Shopify App Store. This makes Shopify one of the biggest companies in the Bitcoin space. Is Bitcoin mainstream yet?
7  Economy / Speculation / How many coins do we think have been lost forever? on: November 07, 2013, 05:59:51 PM
Wild guess, from stories and anecdotes I know of, 20-25%. 

Attrition in the early days must have been reasonably high when they had little or no value?
8  Bitcoin / Press / 2013-11-06 Yahoo Finance : Video commentary on current rally ($15m into BIT) on: November 06, 2013, 10:36:56 PM
That explains quite a lot, $15m so far invested in the Bitcoin investment trust, second half of video. 

That will have moved the needle quite a bit.

9  Economy / Speculation / Coinbase - Bullish sign? on: October 31, 2013, 05:54:26 PM
Coinbase is almost as expensive as Gox now.   Are they are struggling with the influx of new buyers/subscribers, it looks like the number of wallets is up 30k in the last couple of weeks.

“Bitcoins are quickly becoming a popular form of payment online and BitPay simplifies it for internet retailers that want to offer it as a payment alternative, without the need of a deep understanding on Bitcoins,” said Jimmy Rodriguez, CTO for 3dcart. “The built-in BitPay integration is one of the flag features of the new 3dcart 6.0 version.”

These seem to be getting more positive and less condescending.

"Maybe one day in the not so distant future, we will be discussing how far it's come over a pint -- purchased with our Bitcoins, of course. "
17  Bitcoin / Press / 2013-05-18 Pandodaily - A bitcoin bubble could be good for everyone. on: May 18, 2013, 08:45:13 AM

Bubblelicious, Nice piece....

"In the next few years, if the US government doesn’t try to stamp out bitcoin, it will follow a similar course. And when the bubble bursts – if it manages to get to that point – an entirely new currency will have taken root with a vast infrastructure to support it.

First, though, more air must be pumped into the bitcoin bubble. And there’s a whole lot more room before it will pop."

“If this faith in Bitcoin continues over time with a supply that’s restricted and demand that will obviously go up, then you’re talking about a $100 billion or a $10 trillion market,” he said. “You don’t get the opportunity to invest in that every day.”
