Bitcoin is in its younger age and it has started to grow now and its also getting attention from the people across the globe so I don't think that bitcoin will die soon and in fact it will become more popular and stronger currency in future when adoption level will go higher.
Bitcoin is bouncing back right now, it means its already recovering from the previous dump. Also, theres news that all already agreed for segwit which there is no split that will happen. Great to all of us, we will see bitcoin raising in value in the coming days.
Nobody would want a split in the chain because the price of bitcoin will surely go down. It's something that not only users are afraid of, but also the miners themselves. If they let the price of bitcoin go down, all of the coins that they have been saving for the long run will just go to waste. That's loss on everyone's end.
I think segwit isn't fully sure yet, it's just that the chance of having a split has come down. BIP91 just reached 80%, that means that instead of having 95% of the miner signal for SegWit's activation, it will go down to 80%. Miners have already agreed on BIP91 so chain split's chance has went down. You should read more about it
