Everybody is pulling money out of their altcoins into BTC to wait for the hardfork and collect their bitcoin gold. But as long as there are hardforks on the BTC agenda, don't expect a large pullback.
And how long do you think that's gonna last? How many chain splits are there going to be?
There will be no chain or coin split that will happen. Hard fork is an upgrade of nodes in the network and it doesn't harm bitcoin.
While bitcoin gold isn't a result of hard fork instead it's more likely an airdrop that we can get during the hard fork.
That's why many are holding their coins tight to get the equivalent of it. Well, who never loves airdrops anyway?
