When I discovered that there were so many bitcoin forks, and forks of forks, I realized that I wanted a full collection of them :-) So I got  motivation not only get some money from forks, but also collect forks. It's a kind of irrational motivation, just like collecting physical coins for numismatic purposes.
Do I understand correct that some forks can be claimed solely through their own wallet, and this can be done only provided you have synced the whole blockchain, so this is the very reason why claiming some forks (such forks) takes a lot of time?
