Shouldn't have to say this to the STEEMIT community, but just so people don't have any issues besides a transaction fee PUT YOUR BTC IN A NON-EXCHANGE WALLET. I have read 5 articles this morning about exchange's feelings on BTG after the fork, and I have also read multiple things about replay attacks (some say there is protection etc) and other not so good things happening.
During major forks like this, eat the txn fee and put your damn coins in a wallet off the exchange, one that you own the private keys to. I would suggest Coinomi (android) and jaxx (apple/android) I am not super vested in multi-coin PC wallets, I would recommend using the phone ones so when the universe goes back to normal you can use the QR code function and send it back to the thieves... i mean exchanges.
Anyways, Public service announcement over... I will have 0 sympathy for those who decide to keep their BTC on an exchange during the fork.
