If Bitcoin crashed and burned would it most likely be the end of all Crypto currency ?
If bitcoin really do burn out, I think that will not stop the crypto from proceeding. There are a lot of crypto as of today, the 2nd to bitcoin is an example, ETH has so many investors that I think they will continue to support even without bitcoin. Most of the people who support ETH is really focusing on how to obtain them. so I think if bitcoin will fall, ETh will rise.
Bitcoin = e-mail
Ethereum = internet
The internet can survive without e-mail
Edit: In my opinion the above analogy should look more like this
Bitcoin = e-mail
Blockchain = internet
