Ledger's first unsuccessful attempt to provide a BTG wallet suggested a tx fee of a couple dollars to send BTG.  Their revised BTG wallet (chrome app) suggested a tx fee of one penny to send the same amount of BTG.  Does anyone know how to estimate a reasonable fee to send BTG?

Thanks.  I am surprised because my wallet allows me to sign messages using SegWit addresses.

Anybody know of any Bitcoin wallets that support SegWit and have "coin control" features (i.e., the ability to freeze addresses or send BTC from specific addresses)?

I would like to participate in the upcoming Byteball distribution by signing messages with my Ledge Nano S chrome wallet, but ran into a problem.  When I enter my BTC address in the Byteball Transition Bot, it responds "Only P2PKH addresses are supported."  Is this because my BTC is in SegWit addresses? 

I have not updated to the latest version of the Byteball wallet; does it support SegWit addresses?

On that page under "Development version", I found the following series of what I believe to be Linux commands:

git clone git://github.com/spesmilo/electrum.git
cd electrum
python3 setup.py install
sudo apt-get install pyqt5-dev-tools
pyrcc5 icons.qrc -o gui/qt/icons_rc.py
sudo apt-get install protobuf-compiler
protoc --proto_path=lib/ --python_out=lib/ lib/paymentrequest.proto
sudo apt-get install python-pycurl gettext
./contrib/make_locale

If I create an Electrum folder in the persistent storage of my Tails USB, open a terminal in that folder, and enter those commands, will I theoretically end up with a functioning copy of Electrum v.3?

Are you suggesting I run a Core node on Linux because it offers coin control?  I'm afraid I lack the resources and expertise for that.  I can send BTC with the Ledger software wallet but it would mean sacrificing privacy (my main concern) and paying higher tx fees due to the lack of coin control (their software does not try to minimize tx inputs to reduce fees).

Is there any way I can get in on the testing of Electrum v3?

On October 15, Electrum tweeted that 3.0 "took longer than expected, but we are ready now."  Anyone know why it hasn't been released?  Is there a new ETA?

I made the mistake of transferring my BTC to segwit addresses on my Ledger Nano, thinking that Electrum would soon support segwit and provide the coin control features that I need (e.g., being able to send BTC from a specific address). 
Are there any other wallets that have segwit, coin control, and Ledger Nano support?

Thanks.  I'm too paranoid about exposing my private keys to hackers to start messing around with stuff I don't fully understand.

Has anyone been able to use Electrum's "replace by fee" feature with a Ledger Nano?

I discovered another place to try entering the commands shown on the Electrum support page:  the "Console" window of the Electrum program.   So I saved the unsigned tx file in the same folder in which the Electrum program was installed and I copied-and-pasted the "cat unsigned.txn | electrum signtransaction - > signed.txn" command into the console window.   It responded "SyntaxError: invalid syntax."   

Was that the right place to enter the command?

Those instructions are a bit over my head.  

Are you sure it is possible to sign the transaction using the command line when the private keys are stored in a Ledger Nano?

Edit:  When I tried entering "cat unsigned.txn | electrum signtransaction - > signed.txn" in the Windows Command Prompt window, it did not recognize "cat" as a command.  Is there some other place where the command should be entered?

I sent my last transaction with a low fee and the "replace by fee" option enabled, just to give it a try. Now when I right click the unconfirmed tx in the History tab and select "Increase fee", it gives me the option to set a higher fee. But when I try to sign the new transaction, I get an error message that looks like this: http://imgur.com/a/O1vyD

Should this feature work when using Electrum with a hardware wallet? I did not click the "Final" checkbox after setting the higher fee; is that required? I'd welcome any help!

EDIT:  Might the error have anything to do with the original transaction only having one output?

I'd appreciate some help installing the Linux version of the BitCore wallet.   I'm new to Linux but managed to create a bootable USB drive that runs TAILS which I hope will enable me to operate crypto software wallets more securely.  I downloaded the Linux-0-14-1-6.tar.gz file and opened it, which appears to have extracted two folders of files:  "bin" and "source".  The "source" folder contained a .zip file which I also extracted.  However, I do not know how to actually install and run the program.  [I tried to run the bitcore-qt file but nothing happened.]   What is the next step?

Regarding the behavior of bitcoiners, I was surprised by the number of folks who are willing to "invest" in obvious bitcoin-based ponzi schemes.

I am also surprised by the hatred of some bitcoiners toward Coinbase, which I believe provides a valuable on-ramp for newbies who may lack the knowledge and confidence to otherwise acquire and securely store bitcoin.

I was not asking to bet with someone directly.  I'm also not spamming betmoose.  It just happens to be the only way that I know and understand to bet on this SEC decision.  I am actually seeking alternatives to Betmoose that would enable me to place a larger bet.  

I don't anticipate owning enough altcoins to worry about storing them in a hard wallet, and I do not want to use my USB bitcoin wallet to login to websites.   You make a good point about restoring the wallet from seed.  The Nano would require using a safe or air-gapped computer which is less convenient.   Nevertheless, the Nano seems more secure to me if initialized on a safe computer...and if their Android app works well.

I expect to use a hardware wallet for long term storage, making very infrequent send transactions.  [I will maintain a separate less secure hot wallet containing much less BTC for spending.]   With the Ledger Nano, I can keep the "security card" in my safe deposit box (and perhaps a hidden version on my computer) so that if a robber obtains my Ledger Nano and my PIN, he still cannot get my bitcoins.  Why is this inferior to the Trezor or Nano S?

Are the fees the same as BTCe to deposit USD (from America), trade for BTC, and withdraw BTC?

I see you are getting responses from folks who seem very committed to cryptocurrencies.  If you are very certain that cryptocurrencies will outperform other asset classes during the time period before you may need this money (and that you won't get stuck holding the wrong cryptocurrency), then it is reasonable to keep it all in cryptocurrency.  However, I'm not sure it is reasonable to be that certain.   Here is an alternative investment strategy to consider:

10% stocks funds
10% bond funds
15% gold (and a little silver)
15% bitcoin (and perhaps a little alt-coins)
50% Federally insured investments (i.e., treasury bonds, CD's, savings accounts).

I consider this quite conservative.  If you can wait 20 years to cash-in, Series EE savings bonds will yield a government-guaranteed 3.53% annual return; this is hard to beat on a risk-adjusted basis at this time. 

If I were younger and more optimistic about the economy, I would double my stock exposure and reduce my government-guaranteed investments accordingly.

I think Circle is relatively safe and cheap.   ACH transfers of USD from Circle to a bank are not fast, however.
