If BCH network/protocol design is as good as they claim, they don't need to worry about anything and they can rant/promote about their coin after the attack Roll Eyes

Besides, lots of cryptocurrency already attacked and still survives until today.

Even if this attack is a success, I don't think BCH value will be down to the worrying level. They will simply fix it and everything will be same as before. People are not rational nowadays, altcoin like XVG, BTG, EOS, etc. still hold high value despite multiple attacks and/or bugs in their network.

some things aren't fixable!
for example when you have 32 MB blocks and the whole reason why your altcoin exists is to have a bigger block, you can't just fork back and turn it to a smaller size block again.
or when your coin (BTG) is successfully attacked and is easy to wipe its blockchain with a 51% attack you can't do much about it. and it has lost value. it was 0.3BTC at some point and now it is 0.003BTC.
or when your blockchain is more than 1 TB (ETH) you can't do anything about it. it is your blockchain and you can't discard it, you are already centralized.

Hmm,
Sorry but from a technical standpoint ,
if the 32MB is a security problem, but can only be exploited if 32 mb blocks are created,
A hard fork dropping BCH back down to 8MB limit would circumvent the problem.
and even if somehow the BCH blockchain was forever tainted (which is doubtful), they could still run a swap to a new blockchain that had the fixes already included.

As long as their community is willing to support it, it will survive, as that is the thing about all coins, their strength comes from their supporters not just code.
So even if the guy crashes the BCH network and highlights a new security issue, it's supporters are not going to just give up,
thinking that is a serious underestimation of your competition.
Wishful thinking on the segwit-core crowd part , but not realistic thinking.

The #1 thing that gives Bitcoin value is it's certainty and safety.
ANY altcoin is prime to move value from A to B, yet NO altcoin can compete with Bitcoin in terms of certainty, of a solid network that's hard to change.

Chinese Miners control over 51% of both segwit-core & bitcoin cash, both are centralized.

If there is a large enough consensus any Proof of Work blockchain can be changed.
Observe that the btc miners rewrote 24 blocks on March 12, 2013 :

Six hours were overwritten according to the article.

The economic damage was significant, but fairly small; the only monetary losses that have been reported are the $26,000 USD worth of mining block rewards from the 24 mined blocks of 25 BTC that are now forever lost in the now abandoned chain, as well as a $10,000 double spend against OKPay. Aside from the lost mining revenue and this double spend, transactions were not affected and no bitcoins were lost; any transaction that was included in the now abandoneded chain was included in the new chain as well, so any bitcoins that were spent during the fork are now at their proper destinations.
