Both are forking anyway, thats hardly the point. Classic is going for a hardfork while core has a softfork ahead.

In the light of a serious discussion, what exactly is not bitcoin about opt-in rbf?

There are no sending addresses, you can only receive bitcoin via addresses. When you pay bitcoin you use transactions you have received in the past and create new transactions someone else (or you) can use later.

As I said above, stop using shitty services. There is no issue on your end, so you cant fix it. The person that made the transaction needs to change their software.

No, but you should not create a new transaction that needs the funds from the above transaction(s). Creating new addresses are not an issue.

I wrote the raw, unsigned TX for zDavidR (see the flashy red warning at the end of my post). I keep all raw TX I ever wrote on disk for easy reference. I picked that one as example here. Not sure why, probably because it was the first file with different values for vout I found.

Dont use services that have shitty software to handle payments. Its not your responsibility to fix their software. The only thing you could do now is to follow the chain to the first unconfirmed transactions (it forks off into at least two chains after a while). Once you have a nice list of transactions, get the raw formated version and broadcast them via a website that allows you to do so. From the last instance I have see, I think you can easily expect >>400 transactions to be involved. Might take a few hours by hand.

You are creepy.

Did you even look at the TX?

10000 Satoshi for 226 - 373 byte transactions is perfectly fine fee wise.

The ponzi you expect payment from has bad software to handle the payments. They use unconfirmed coins to create a TX on top of it. The TX on top can only confirm when the earlier is confirmed. This can be in the same block.

Lets take "bx2.club --> rajat08" as an example. In blockchain.info's advanced view[1] you can see a little red "U" for unconfirmed. If you click on the link labeled as "output" next to it you will see another TX, which is unconfirmed. The chain of unconfirmed transactions that depend on eachother in this case is rather long. I would suggest you stop using the shitty service that created the TX, but seeing that it is a ponzi I have little hope for you.

I have run a full node on a window 7 box for over 2 years now. This is not a common Windows issue. Changing the OS might not be a solution. Keep in mind they just switched from Win 10 to 7.

Whats your collateral?

No, most wallets only take confirmed transactions into account.

You dont have many options.

#1 you wait
#1.1 ...until the transaction is confirmed, which will probably require you -or someone else- to push it from time to time
#1.2 ...until the network has forgotten the transaction and create a new one with a higher fee.
#2 you dont wait and try to double spend it with a higher fee. Which has a low probability to work, because you need time for the network to forget about the old TX in order for the double spend to get confirmed.

No reason to give up free speech just because you have nothing to say.

Or in how to do it:

#1 Open Mycelium, swipe left to your accounts.
#2 Tap the account you want to export
#3 Tap the 3 dots (top right) and select Export
#4 Read and understand the warning and hit "yes"
#5 on top switch from "public" to "private".
#6 Read and understand the warning and long press it
#7 It will show a long code starting with xprv keep that open, thats your master private key. It is all your private keys for that account.
#8 open Electrum
#9 File -> New/Restore
#10 Set a new, e.g. Mycelium1
#11 Select "Restore a wallet or import keys" for the upper option and "Standard wallet" for the lower option.
#12 Enter the master private key and follow the rest of the steps.
#13 let it sync, you now have all private keys in electrum and see which still have a balance and which not.
#14 Rightclick an address you want the private key for and select private key. It will ask for a password and show it to you.
#15 collect all the private keys you need
#16 repeat the above steps for all mycelium accounts
#17 once you have all private keys import them into a new electrum wallet, but instead of the master private key use your list of private keys. One on each line.
#18 you now should have all address with balance in a single wallet ready to spend.

I think I just had this[1] thread in mind. Alright more serious. They are spread over different wallets so you need to find out if you can export the private keys from the wallets and how. Which wallets did you use? Are they all mycelium?
