So I suspect that what I'm going to describe below is pretty stupid. I’m just hopeful that there is some way that you can help me.  Here’s what I did.
 
I make a regular donation to a charity. In May I decided I was going to put this donation into bitcoin and then around Christmas time give the charity whatever amount that turned into. Well it’s December and I need to convert this bitcoin into USD so that I can give it to them. I did ask if they took bitcoin directly but they did not have any way to handle that. So my only option was to convert to USD.
 
I stored the bitcoin in one of the accounts in my KeepKey accounts and I generally access my KeepKey using Mycelium on my android phone. I got an address from GDAX and then created a TX to send. I chose a low miner fee of 47 sats/byte thinking that this would confirm in a few hours.
 
Well 6 hours later it hadn’t confirmed and I was getting impatient. So I tried to create a CPFP transaction w/Mycelium to push it through. But I didn’t have enough funds remaining in the account.
 
And this is the part where the stupidity starts to overflow.
 
I decided that since the TX hadn’t confirmed yet, I could just delete it from the wallet, get a new address from GDAX, create a new TX with a higher fee and send it. Which is exactly what I did. This time choosing 158 sats/byte. But the 2nd transaction never showed up on blockchain.info. And when I checked on different block explorers only one showed the transaction: blockcypher. And it showed it as being a double spend.
 
My guess is that the 2nd transaction hasn’t been propagated to the rest of the network.
 
So now I’m stuck. I’ve got one transaction out there that's been unconfirmed for about 20 hours, and a second transaction that's not propagated to the network. And, interestingly, when I plug my KeepKey into the "official" KeepKey wallet, it sees the first unconfirmed TX. But Mycelium sees the 2nd one.

What options do I have? Do I just wait? Will the 1st TX eventually confirm? Or are minor's rejecting it b/c they see a double spend attempt?

Here's the first TX that's visible just about everywhere:

Here's the 2nd TX that's only visible on blockcypher:

Hi,

I use blockchain.info. And they have a feature that allows me to create what I think of as "sub wallets". I can then store different bitcoin balances in each of those sub wallets.

I have imported my blockchain.info seed into Electrum. I did this so that I can still transact my bitcoin in the event that blockchain.info is down. However, I'm not seeing any of the transactions or balances on the other "sub wallets". I can only see transactions and balance on my "main" blockchain wallet.

How do I get Electrum to recognize these "sub wallets"?

Thanks,

Hi,

I use blockchain.info and I've been able to create what I think of as "sub wallets" within the main wallet. The idea being that I might store different bitcoin used for different purposes in each subwallet and then be able to track balances for each purpose.

I also use the seed from blockchain.info in a desktop wallet (Electrum) in the event that blockhain.info has some availability problem. (Yes I know there's a risk doing this.)

The problem is that the "sub wallet" addresses don't appear to be showing up in Electrum. And as a consequence Electrum only has the balance of the default blockchain.info wallet.

Does anyone know what these "sub wallets" are and how I would make sure that they show up in Electrum?

I get to them by going here: https://blockchain.info/wallet/#/settings/addresses

Thanks.

Ok. So I just finished reading "Mastering Bitcoin". And I'm a little confused about transaction privacy.

I understand that I should always use a new bitcoin address every time that I receive or send bitcoin. I think I understand the reason: because if I pay my rent using the same bitcoin address that I use to receive my salary, my landlord could go to the blockchain and see how much money I receive into that address and thus change my rent accordingly.

But I'm a little confused as to how my landlord isn't able to know this even if I use a new bitcoin address.

When I send bitcoin to my landlord, my landlord can be confident that I'm not double spending some money because his wallet can trace back the origin of the of the money I sent and verify that it's not already been spent. As I understand it, the whole beauty of bitcoin is that anyone can trace back all transactions to the coinbase that created them to confirm that double spending hasn't occurred. This is one of the functions of being a node on the network.

Well if that's true, can't my landlord trace back the transaction chain one level deeper to see how much was sent to me? If I pay my landlord with bitcoin that came to me via my salary, then isn't my landlord going to be able to see my salary amount from the previous transaction in the chain?

Even if all new addresses are used in my next paycheck:

a) from my employer
b) to me
c) from me
d) to my landlord

Can't my landlord just simply trace back one transaction to see how I received that bitcoin, and then make some assumptions about my salary?

I must be missing something. Am I missing something?

I have downloaded and installed the 0.12 bitcoin core client and am running it on my very old linux server at my home.  I'm doing this not because I expect to win any BTC doing this. I'm doing it because I want to participate in the network. In the hopes that I would actually help in some way.

But it strikes me that all of my CPU cycles will simply be wasted if I never contribute a winning block. Basically, at this point, my server will receive and forward transactions across the network and that's it.

Two basic questions:

• Apart from forwarding transactions, is there any value in my running the code?
• If not, is there a way to disable mining and just do transaction forwarding?

Thanks.
