I'm quite sure that it will be around for a long time, even now people are always saying that eth is a good long term investment, of course with the right entry price and just blindly invest on it. I mean it's a major coins and a very popular to boot, so it's hard to imagine the price to go down to zero. Still tho, we really can't say never, all possibilities are open in crypto world. So better not believe all those fuds.
