Quick screen how-to:

Screen should be installed if you followed the steps on the first post.   Otherwise install it first.

#start up screen in the background

#attach to screen (from any terminal or ssh session)


#my four most used key combination in screen

#detach from screen
ctrl+a, d

#resize screen to fit current terminal (when one is attached elsewhere)
ctrl+a, shift+f

#create another window
ctrl+a, c

#rotate between window
ctrl+a, n

You can start reading over the info over here on this thread:

Follow the links there to get specific rules and details to sign up regarding each campaign.

Based on your screenshot: should be something to the effect of "apt-get install libncurses5-dev".
If it's not found, search for it with "apt-cache search libncurses"

Does your config file have the basic four lines to enable rpc?

server=1
rpcallowip=192.168.1.*
rpcuser=<username>
rpcpassword=<password>

would transaction you posted be the "sent" part or the "sent back" part of concern. 
we are looking to see a second tx id since you mention sent back.

I haven't seen any statistics regarding minimum relay fees lately.   With the amount of potential spam about, I suspect it has become common for node owners to set one.   Will that low a fee even propagate to a block solving node?

You only own the address if you have control over the private key associated with it.   The wallet that generated that address is where your private key is kept should have an ability to sign, otherwise you need to move your key in order to do so.   Be carefully doing so.

I'm emphasizing legacy over profit.   One of the point is that it is a collectors item.   If I had a wealthy uncle that left me bitcoins, it would be awesome receiving a physical coin.  Like getting a rare valuable 1960 rookie card.  You can't decide if you should keep it or cash it out.   It's an effective way to be remembered.

Not sure if it would have made a difference unless you had the willpower to hold.   

Why?
Increase in bitcoin price, Increase in number of bitcoin transactions.

Possible solutions:
    1. Wait for bitcoin price to drop and the $ per tx will fall too. 
    2. Wait for bitcoin network to become less congested.   
    3. Wait for changes to go into play allowing more tx to fit into a block. 
    4. Take the risk at lower fees and experiment with the so called accelerators.

#3 is probably the longer term solution everyone is watching out for.

Good call.   I had forgotten I turned that on to be able to choose a custom change address.

Space is not a special benefit the way you are currently presenting it.

Other part of the equation:
- Equipment Costs
- Equipment Repair Costs (worth reading up on.. can be a surprise)
- Difficulty increases.

Except for DC space simply being there, do you have access to (free) something that makes it more beneficial compared to just sending miners over to a hosting site that does $0.09 / KWH (including cooling)?

Edit:

Here's a little calculator tool I put together a while back:

Once you go over half the [$/KWH] column, risk increases quite a bit.

I don't know starting what version, as I send with Bitcoin Core (0.14.1), there is a button that sais "Inputs" with a label indicating automatically selected.   If you click on that button, you can choose which inputs to use.   Otherwise the wallet will, as indicated, choose the most appropriate ones for you automatically (from possibly a change address).

If you search any address in https://blockchain.info for information, there will be a big QR Code on the right side there you can use.

Transactions are built upon previous transactions, where input = outputs.

The transactions you listed used the output from
https://blockchain.info/tx/0bb7c84fc787e64f134198726eaacf4ffd27fd8c993197de67ef0a7ae24634fa

as input and create two new outputs.

0.00950364 BTC to destination
0.04220857 BTC to a change address in your wallet
0.00049636 BTC as fee.

Looks like two entries slipped through a summary update in the previous page of posts.

Head over to the marketplace auction area.   There are a few creative folks over there thank make physical coins with security holograms protecting the private key.   You have to destroy the coin and hologram to get to the key.   It's a good way to pass bitcoins on as a legacy item without simply revealing the private key to the handler.

Fee amount can be any value.  Your wallet may recommend a value relative to what everyone else is putting in so that it gets selected first or reasonably first to be added in the next few blocks.   At the moment there are more transactions floating around than there is space on any one upcoming block. 

+0.5 = vh

This predicting task is tricker than it looks.   Especially when there is a chance to shift direction.

Read through the first post in this thread to see if there's anything different in the build instructions you have.   Then focus in on the troubleshooting notes in the Q&A section at the end of that post for some help isolating the possible issue.
