How did people claim it last time? Thought private key was suppose to be, well, private.
it is still "private" and should always remain private. but private means you are the only person having access to it not anyone else. like having an account on Coinbase as your bitcoin wallet, you won't be having any access to private keys that way.
the way people claimed BCH was either depositing their bitcoin on exchanges like bittrex prior to the fork so that bittrex and others give them the BCH tokens automatically (this is risky though).
or they waited for the fork to happen, then downloaded one of the BCH wallets, imported their private keys in that and claimed their tokens.
I tried jaxx wallet but hell the transaction fee is very high (if I know i wouldn't use that shit).
i guess we are waiting for next news about bitcoin gold and i hope we can get 1:1 like bch aka bcc yesterday
have you try mycelium? because if i see in my mycelium, we can set the fee and i always use normal and the fee have many option and we can choose what is suit with us. you can download it at playstore but i don't know if there is any software for computer.
