Bitcoin XT, Unlimited, Classic & SegWit...should be categorized as planned hard fork/network upgrade.
Of course, I believe you and will do my best to adjust all info in the opening post, but I will wait for more comments because I knew there will be a lot of discussion around this subject and of course a lot of different points of view or information.
As you can see, there are links provided (overall) to sources and all of them describe these once mentioned by you, as hard forks. I had no reason not to believe several sources, that give the same information, so if you can provide any other sources, with different/counter information and conclusions, I would be grateful.
PS
Already removed the word "hard" in a couple of sentences to adjust accordingly to provided information. So, now is only "fork" which can mean soft or hard.
Now OP i have a task for you. Tell us an easy way to claim all that shit...
This is not the purpose of this thread, but it is enough to search in Google for a query: "how to claim BTC forks?" and you will get multiple tutorials.
Of course, only a few of these forks are still worth something and a decent website with guides/explanations is here:
https://99bitcoins.com/bitcoin-forks/Always check everything three times and remember that claiming Bitcoins from an old wallet can be a real threat to your security.Its necessary to export the private keys from your old wallet using a special format. In most cases, a file will be generated that contains all your addresses and their respective private keys. Certain wallets, wont allow you to export the private keys. In such cases, its necessary to enter your hardware wallets seed phrase into a tool (such as Ian Colemans BIP39 Tool), which should be run offline. Another option is to import your seed into a compatible HD wallet, such as Electrum.
