I've got a good amount of BTC in various exchanges and wallets. Each of these exchanges needs username, password, and 2FA code from phone to access. I'm looking for suggestions on a solution that, in the event of my untimely demise, my wife would be able to access everything. Let's throw in the option of my phone being destroyed along with me. I feel it was be near impossible for her to reset all the 2FA's. I'm thinking of typing up some instructions, laminating them, and storing in safe place. Thoughts? Suggestions? TIA!

Awesome answer! Thanks! Had no idea inputs & signatures took up 70% of the transaction.

I keep seeing things like "SegWit addresses are lower tx fees". Can someone explain why/how that is? Why does sending BTC to address A (old style) vs address B (SegWit style) incur higher tx fees? Aren't both transactions going on to the same blockchain and being processed by the same miners to be added to the same block?

Thanks for reply. How can I generate 1000 addresses in Armory
In the Wallet properties dialog, there's a figure next to the Addresses Used field. Click it. You have to be in Expert mode. export/copy just the public address?
Grab the watching only copy of the wallet. But isn't a watch-only copy just another wallet file (ie: not paintext)? I'm looking for something like CSV or just a text file with just addresses.

I want to use Armory to handle about 1000 addresses that I'll be using for an online store. I've read the best practice is to generate the addresses offline, and only keep the addresses (public key) on the webserver.
How can I generate 1000 addresses in Armory and then subsequently export/copy just the public address?

Any chance of this ever working with Google Sheets? I don't have MSExcel.

Accordingly, with the blockchain, we are able to store our data in digital form.
Explain this in more detail. Explain how, using the blockchain, I store the fact that I own a car, house, etc. I want to sell you some concert tickets. Explain how the blockchain secures this transaction.

Interesting. I even just watched this presentation by Goldman Sachs, http://www.goldmansachs.com/our-thinking/pages/blockchain/, and they too gave the example of buying/selling a car and some concert tickets. I'm curious how they think the blockchain will be used to immutably assure sales, accounting, and transfer of ownership.

I've been "around" bitcoin for several years now and one thing has always puzzled me. One of the things I tell people new to BTC on why it is so great is when I describe the purchase/sale of a car, and how that contract goes on a ledger that cannot ever be changed.
I give this example, but I have no idea how this would actually work. Can someone describe the process to me? In order for it to be legal, all the documents would have to be signed and sent to the state (I live in TX) to properly transfer ownership.
Would I scan all those documents into 1 PDF and somehow "attach" them to the block containing the transfer of 5 BTC to my address (assuming I'm selling the car)?
If I had to go to court to prove that I sold/bought said car/property to/from person X, how would the blockchain be useful to me in proving my case?

Hello. I transferred about 11475 SJCX from Counterparty wallet to Poloniex almost 18hrs ago. The BTC block has been confirmed 96 times yet the SJCX are not showing up in my Poloniex account. Here's the block: https://counterpartychain.io/block/447145Any ideas why the SJCX hasn't appeared in my Poloinex account after 18 hours? Thanks!

When getting the private keys of imported addresses in blockchain.info, you'll get completely different private keys instead. Follow the instructions here to convert it. Awesome! Thank you! Had to bust out a windows vm for this but it was painless otherwise.

Hello, I've got several addresses in my blockchain.info account. I decided to import them into Electrum. I used the private key from bc.i for address 1xxxx.... but when I imported it, the resulting address showed 1yyyy... It was completely different! I even re-imported the same private key back into bc.i and it too imported a completely different address (same address that Electrum showed).
What the heck happened? Can I no longer use those older addresses? Some are vanity with custom prefix that I'd like to keep using.
Yes, they are all at least 2-4 years old. Did some calculation standard change recently?
Thanks!

Hello, I have 2 ASIC Cube miners and 2 USB YellowJacket miners. It costs more money (electricity) to run them than they produce. What should I do with them? Just throw them away? Does anyone want them? You can have them if you cover shipping costs. PM me.
Cheers, Matthew

Hi all, I purchased an ASIC Block Erupter cube back in January off ebay. It came shipped 2-day USPS Priority. No damage at all. Worked great. Time to sell it (too much noise, too much heat, too much girlfriend complaining, etc).
Sold on ebay. Shipped in same box it came in. Even added some extra air-bubble packaging. Got USPS insurance for my original purchase price because if it gets damaged, then I'm out the hardware and the refund to my buyer.
Sure enough, none of the cards work when buyer receives. Submitted insurance claim. Buyer takes cube to local USPS for inspection. 20 days later, claim denied because "no external physical damage evident." I have one more appeal.
Just because a car has no external damage doesn't mean the engine block is locked up right? I can't exactly explain to a USPS employee how to turn it on, configure it and see all the X's mean it's broken.
Does anyone have experience with this? What can I possibly write in my appeal letter that will explain to them how this is damaged beyond repair?
Thanks!

Hope people are still monitoring this topic. I'm attempting to test this out and not having much success. I used two of my own existing addressed to do the test so I can't/won't provide my private keys. Here are the steps I took: 1. New MultiSig Address. Testing a 2-2. 2. Got this multisig address: 3BubMVeGDzvhZyJ1iCS8vpjKgDSfT18Dh1 3. Sent some btc from addr1 to the multisig. This worked. 4. Verified the redeem script. Says 2 signatures from both public keys are required. 5. Signed redeem script with private key of addr1 6. Copied the result of #5 back in to the upper field and pasted in private key of addr2 7. Copied the result of #6 in to Verify page. Shows the original transaction id, checkmark for redeem script, minimum number of signers 2 and number of times signed 2. Shows me the correct output address and the amount. 8. Copied the result of #6 in to Broadcast. TX Rejected. 9. Reattempted steps 5-8 using keys in reverse order. Same result. So now I'm stuck. Not sure what to do. Thanks!

Simple question: can I run multiple/both scrypt and sha256 miners at the same time with bfgminer? I have 2 Gridseeds, 4 Rockminers and 1 RasberryPi. Can I plug all 6 devices in to 1 USB hub and run 1 instance of bfgminer? If yes, how would I configure bfgminer to use one pool for the Gridseeds and a separate pool for the rockminers?
Or do I need to run two instances of bfgminer, one for the gridseeds and one for the rockminers?

Hey Dogie, I have 3 of these cubes and two Corsair AX850 ( /e7qEGt]http://[Suspicious link removed]/e7qEGt). Right now, 1 PS powers two cubes and the 2nd powers the other cube. If each cube only takes 200W, why can't I power all three cubes with 1 PS? I don't run overclocked. Is it somehow more efficient with my config vs running 3 cubes on one PS? If not, how can I accomplish running all 3 on one PS? If each cube needs 6x 12v and 6x GND, can I use a pinout diagram and make custom cables to provide this from the other, unused, slots on the PS?

Hi all. Just got my Gridseed 5-chip "orbit" in the mail. Attempting to use it with Mac OS X. I've followed nwoolls's blog article and even loaded the FTDI kext driver. No matter what, the Gridseed keeps showing up as: [2014-03-31 10:29:02] lowlevel_scan: Found vcom device at dev_t:0d000012 (path=/dev/cu.usbmodemfa14141, vid=0000, pid=0000, manuf=(null), prod=(null), serial=(null))
Can I still mine? How do I tell bfgminer to use this device? GridSeed devices are not supported in BFGMiner yet, which is why it is not able to detect them. Support will be in 4.0, due out soon. Hey nwoolls, I thought your blog article said to use the --HEAD when installing because it does provide support? Did I misread that?

Gave up on trying with Mac OS X. Used this guide and got it running on raspberryPi.
