1  Economy / Exchanges / Always getting HTTP 500 error on HitBTC Downloads on: October 17, 2018, 04:02:46 PM
Over the last week whenever I try to download transaction history been getting HTTP 500 error. Have tried in Chrome and Internet Explorer, tried clearing cache, tried clearing cookies and other site data, turned off pop up blocker, turned off firewall and virus blocker, even tried on 3 different computers. Always get error.

Submitted a bug report and they claim site is ok. Anybody else having this problem or know how to fix?

3  Bitcoin / Mining support / Can't change default pool data using browser interface or in bmminer.conf??? on: December 23, 2017, 10:04:53 PM
Have an 8.5 Th/s R4. When I try to change the pool URL from the default antminer pools and hit Save&Apply all fields go blank and doesn't connect to anything.

Can do the R4 reset button and antminer pool settings come back and mines fine to antpools and resets to root/root. So thought I could use PuTTY to go in and modify the /config/bmminer.conf file to replace the antpool data with my pool and reboot. But when I try to log in with the default root/root I'm told invalid password even though it lets me log into miner from browser using root/root. But even in browser when I try to change password using "root" as current PW, it tells me invalid password???

Bottom line is I can turn on and connects and mines fine to antpool but I can't change the pool settings.

Anybody see before and know how to fix?


4  Alternate cryptocurrencies / Altcoin Discussion / Is it Possible to Verify MyEtherWallet.zip Download is Authentic? on: December 07, 2017, 03:41:20 PM
I downloaded etherwallet-v3.10.9.2.zip to put on my cold computer, but don't see a PGP signature or any hash to verify the file is authentic.

Am I missing something?

Is there anyway to verify authenticity?

6  Alternate cryptocurrencies / Altcoin Discussion / Icebox for ETH address generation using dice and an airgapped computer on: November 23, 2017, 03:34:33 AM
I just don't trust computer generated random numbers and want to generate ETH addresses with physical dice.

Icebox allows you to for example, use 5 dice rolled 10 times to create a user-defined string that is hashed together with a random string for a guaranteed 128 bits of randomness in your seed.

See https://github.com/ConsenSys/icebox for details.

Has anyone used? Is it trustworthy?

How can we tell if code such as this has been reviewed and is not a con?
7  Bitcoin / Electrum / Using old XP computer for cold storage - how much longer? on: November 22, 2017, 08:22:06 PM
I'm still using an old XP computer for cold storage and to to sign transactions prior to broadcast. Currently running full install of electrum-2.9.3 using chrome and it currently works great with no problems.

Just wondering how much longer electrum will run on XP and if it's time to set up a cold computer with Ubuntu or some other more modern OS?
8  Alternate cryptocurrencies / Altcoin Discussion / Anyway to create truly random Ether address using dice on: November 22, 2017, 07:36:09 PM
I use the trusted bitaddress.org loaded on a cold computer to create a truly random (not computer based randomization) bitcoin address using dice (actually one die) to generate 99 B6 values for my private key and then using its sha256 routine to hash them for the public bitcoin address.

Tried looking for something similar to generate truly random ethereum addresses without any luck.

Does anybody know of a similar trusted method to generate truly random ether addresses?

9  Bitcoin / Electrum / Is there a limit of transactions/address that Electrum can handle? on: August 06, 2017, 10:20:38 PM
I've never had a problem importing private keys until I tried one with 770 transactions within its address. Electrum just keeps processing and seems to stop responding.

Has anyone else seem this problem and is there a solution?

Or, does Electrum have a limit on the transactions/address it can handle?
10  Bitcoin / Bitcoin Technical Support / Address with 770 small transactions, Armory and Electrum can't handle - Help on: August 05, 2017, 08:43:09 PM
Have 5+ BTC in one address made up of 770 small transactions. I want to move the entire contents to a new address. Armory will only allow me to send 0.1 BTC at a time (says too many small transactions if I go bigger) and the fees to transfer all 5 BTC would be outrageous. I tried importing into Electrum and when I hit the send key it just sits there and processes forever when I try to send it all. I even tried sending just 0.5 BTC from Electrum and it does the same thing.

Is there a wallet that can handle?

Would importing into an online wallet work better?

12  Alternate cryptocurrencies / Service Discussion (Altcoins) / Trust for Exchanges Currently Accepting BCH on: August 03, 2017, 04:28:53 PM
Anyone out there that's actually deposit BCH into an exchange and can you please relate how it went?
13  Alternate cryptocurrencies / Mining (Altcoins) / Anyone Switching from Mining BTC to BCC/BCH? on: August 02, 2017, 02:02:16 PM
Wondering if BCC/BCH mining could produce more blocks and be more profitable than BTC mining.

Anyone doing or looked into?
14  Alternate cryptocurrencies / Altcoin Discussion / BCC/BCH Wallet Reviews on: August 02, 2017, 04:12:35 AM
I've transferred my BTC to new addresses (kept the sending address private keys) and am now ready to move my BCC/BCH. I'm trying to decide which BCC/BCH Wallet to use.

Is there a review of wallets anyone can recommend?

Or, personal success stories you've had with BCC/BCH wallets that you can share.
15  Bitcoin / Development & Technical Discussion / Odds of generating an in-use address vs. odds of winning powerball jackpot on: January 10, 2016, 06:05:19 PM
Does anyone have a comparison of these odds?

What are the odds of using a totally random method of generating a bitcoin address to come up with an address that's already in use vs. the odds of hitting the powerball jackpot?

Which is more likely?

If odds of winning powerball better, would like to see expressed as odds of generating an in-use address with bitcoins the same as winning x powerball lotteries in a row?

I know we would need to know the number of addresses that have funds in them and would need to make some assumptions. Would like to hear educated estimates on odds from math gurus.
16  Bitcoin / Bitcoin Technical Support / Running latest core but node doesn't show up on node check on: January 08, 2016, 05:17:30 PM
I'm running Bitcoin core 0.11.2 either as the daemon through Armory or sometimes using Bitcoin-QT. When I look in QT it will show that I'm up to date and connected to 8 nodes. However, when I search for my IP in blockchain.info I don't see it and when I check my node on https://bitnodes.21.co/ I get MyIP:8333 is unreachable.

I want to contribute to the network and thought that I was but now I'm wondering if I'm a read only node and port or firewall settings are keeping me from contributing as a full node.

I have no problem quickly broadcasting my transactions through Armory and receiving transaction info.

Why doesn't my node show up?

 
17  Bitcoin / Bitcoin Technical Support / Getting rid of unneeded blkxxxxx.dat or revxxxxx.dat in core after re-indexing on: December 31, 2015, 08:49:58 PM
After power loss and having bitcoin core re-index blocks on drive for about 15 hours, I now have a rev00000.dat ... rev00409.dat for each blk00000.dat ... blk00409.dat file.

Any easy way to have bitcoin core get rid of unneeded files or to manually do without messing things up?
18  Bitcoin / Hardware / Underclocking and undervoltage methods for S3 and S3+ on: March 09, 2015, 05:57:31 PM
I've seen this discussed in many pools and topics and was hoping we can consolidate. If you know of good info or studies regarding whether it's worth doing, or steps on how to do (including firmware upgrade order and settings), things to look out for, etc. please post the info or links. Thanks.
19  Bitcoin / Bitcoin Discussion / Is old 3.5 floppy safer than USB drive for cold storage? on: October 06, 2014, 05:15:34 PM
With the news on USB firmware hacks I was wondering if I should add a 3.5" floppy to my online computer to transfer from my cold storage old XP computer that already has a floppy. Would it be safer?
20  Bitcoin / Development & Technical Discussion / I found a block but only transaction it contains is the 25 BTC mining award??? on: June 04, 2014, 10:00:06 PM
While mining in the slush pool, I was credited with finding my first block (304223). Who-WA!

But when I look at it on blockchain it shows 0 transaction volume and 0 fees. The only transaction listed is the 25 BTC mining award. I've never seen a block like this before and didn't think it could happen since the purpose of mining is to create blocks of transactions. Is this unique or does it happen a lot?
