Obviously Bitcoin won't die. Just like the stock market, bitcoin too is subject to ups and downs in price. It is the belief of people that makes Bitcoin stronger. Every time the market falls, people consider it the right opportunity to invest and make money, and I am sure that a lot of people would take this low price as an opportunity to invest in bitcoin.
Also, going by the past trends, bitcoin usually upscales towards the ending quarters of the years. Even in 2017, it was the last quarter that resulted in such a high price for bitcoin.
So just sit back, invest, and then watch the market go up.
People can be very dramatic especially when it comes to their money when the price of bitcoin is going up then everyone is very excited and thinking that this is finally it and that bitcoin will change the world, but now that the price is going down everyone is very depressed and think of the worst possible scenario that they can imagine, like always the truth is in the middle of those postures, bitcoin is not dying and will not die in a long time, but there is still a lot of work to do before bitcoin is able to change the world.
