it depends on the exchange, whether it supports the hard fork or not.
Well Coinbase & Co will see customers moving elsewhere if they will not list a coins that is popular
as they try to kill segwit off in an effort to avoid having to share the bonus payment with clients who
have a BTC wallet with them and this is why we get so much propaganda about this fork
BTC miners with insane fees will crash the market and send the price down so this new fork tomorrow
is what you call a self inflicted wound if you ask me.
I will not be hold to ransom by these miners and mining is not my thing but even I will run a full
node for segwit if i can on just a I7 laptop so the BTC miners get payback for ripping me off.
Don't push me, I push back!
