You're pretty right. Not only bitcoin, but doge also like that. From there we should be able to think, not always when the founder leaves, a platform will fall. Support from the community really can make dogecoin continue to live until today, especially with ethereum which has a community greater than dogecoin.
if the community remains strong. of course it will keep eth on the market. the most important thing is, the community does not release their assets. as long as there is support from a very strong community, it will be a big step in supporting ethereum in the market.
