Survival is up to the people. It's not the currency/asset itself, that was proven to be successful after the first transaction between Satoshi and Hal Finney. Bitcoin now lives and breathes at a level equal to how the people hold and use it.
But I do not recommend anyone to buy it, I would only tell my friends to sell it, dump it, collect it, whatever they can do but DO NOT ever buy it once.
This is an excellent recommendation. Buying in smaller increments over time are best to ensure you're getting the most efficient price possible...the investment world calls it dollar/euro/yen cost averaging.
