It depends if exchange support split during the hard fork..
Bittrex, kraken will support split and everyone who holds BTC will get BCC
As far as i know, Poloniex not clear with their terms of supporting hardfork
So i would recommend, better to move your BTC to hardwallet or soft wallet like electrum
not only Bittrex and kraken.Bitfinex also support it as far as i know.
because they're listing Bitcoin Cash in their market BCH as its ticker
I am on multiple exchanges and some have come outright and said after the split, 1 BTC holder will have 1 BTC + 1 BCC after split...some havent addressed this question other than saying they wont support BCC...
What about online vs offline vs exchange wallet...will all BTC holders regardless of location now be credited with 1 BCC in this scenario? or just those who hold BTC on the exchanges mentioned above?
Nobody gets 'credited'.
The BTC blockchain will be copied on 1 aug to a new chain. So whatever BTC you hold, on the new chain you will have that amount in BCC.
Can you explain a little further for me? If I have btc in cold storage what exactly happens to them after a fork? Does the original btc coin amount remain the same?
First of all it's very safe for you to move your wallet into cold storage/offline wallet or you can trust your money with them(not recommended),
For Example :
you have 2 Bitcoin and you keep it in your coldstorage/offline wallet,when the time comes we will see chain splitting (i called it branch of the tree).
it's recommended to keep it in your own wallet because you have a private keys,
that mean after splitting we will see another clone of Bitcoin itself we called it 'Bitcoin Cash',if you keep it by yourself you have an access to your clone,a key from your access to your clone are your 'Private Keys'.
How about it? understand ?
