But like how do you claim it? How do those keys get allocated to you?
Have searched and read different stories...
If you own bitcoin at the time of any fork, you already have the private key of your public key on the new forked blockchain because its exactly the same key. What happens is a duplicate of the blockchain is created; an exact replica. The only difference is the blocks after the fork will have different characteristics. Your private key is still the only one which can unlock your public key
If you understand this concept, you will know that even if every two weeks a hard fork occurs, your two year-old private key will still work if you held bitcoin at the time of the initial fork, so you can claim all the coins that were forked since the initial fork, provided you DID own bitcoin at the time.
How do you claim, that's up to the owners of the new coin, they'll usually create an app or some exchanges will start supporting this new coin.
Be VERY, VERY careful!!! Your private key can unlock all previous iterations of its corresponding public key on any previous iterations where said public key was used.
In other words, if you import your private key to
www.comeclaimfortehlulz.com, they can then go back and scan all other blockchains (your coin's fat's grandfather's great-greatgrandfather, etc)...Example, if someone gets hold of your bitcoin cash key, he can not only steal your bitcoin cash, but also your bitcoin core.
