Altcoin will drop by price and btc will be high as usal.
So buy now and donot re great.
A hard fork means your BTC would now be in both blockchains; but it is simple common sense that one of the two ledger must be invalidated in order that bitcoin is to be trusted - and survive. If the two forks last for years and I have my UTXO (unspent coins) in both ledger, that means both ledgers have been compromised. One must die off! Or one becomes the alt coin.
not at all. altcoins have survived for many years and their survival never meant bitcoin to be invalidated. they remain as an "alternative" and the main thing forever will remain bitcoin until years from now something better comes along.
these forks are also temporary hiccups. after some short time they will just go into the list of "failed attempts" beside hundreds of others.
