I really do believe that if Bitcoin was to die, it would have died a long time ago. Sure it might drop in price but this technology will be around a lot longer than you think.
I don't think it's possible for it to die completely but who knows it could go to $50k or $5.
Price like that won't happen, don't worry. Amount of assets invested in bitcoin is already too great to abandon this project just like that. Big players won't let it die like that, and with their help we could be able to push and pump price to reasonable value.
I agree it's not about to die. It's got enough momentum to be around for the foreseeable future. But it could see some changes in time if it were necessary. Many will copy or implement their own versions (read: blockchains) but they're not about to replace Bitcoin.
