First of all , BTC is the father of all other Crypto-currencies. It can be easily understand be observing the crypto-market when bitcoin make it moves. Now its all about the money and when the term money cross the road it comes with the most valuable term which is trust. if btc any how dies, which is possible theoretically but not practically, whole market gonna crash down in a single week.
Now the main topic are btc gonna be dead in time?
answer is no. Btc can be let down to 5k. or 1k whatever its gonna be hit the 10k again. because, the user and its acceptability is rising not decreasing. it facing hard time cause a huge amount of investment have been withdrawn from the market. and those are gonna be back into the business again for sure. so give it some time.  and put your trust in it.
