From what i gathered my BTC have to be on a wallet, where i am in controll of my private key, right?
Yes. If you leave your coins on an exchange or webwallet, it's entirely their decision whether or not they'll choose to give you the forked coins. I've had no dealings with Binance, so I can't say if they would or not.
- But what if my BTC are on my trezor hardware wallet? There i only know my 24 seed words.
That's fine. As long as the blockchain shows you own those coins at the time of the fork, the forked chain will automatically show the same. Just be careful with those seed words. If your device has any keyloggers or malware when you type them in, or if you've inadvertently installed a malicious wallet client instead of a genuine one, you could potentially lose your funds. Scammers do take advantage of forks to defraud people. Be incredibly security conscious if you're dealing with any large amounts you can't afford to lose.
Binance is usually pretty good at giving away forked coins, but they're only really going to do it for forks that have a good amount of a movement and publicity. I doubt that this is one of them.
I'd keep my coins in a place like electrum, or any wallet which allows YOU to have your private keys and then handle it as you have to after the fork.
Goodluck and be safe with your keys!
