There is a good use of hype at times for the short time traders and profit takers. Most of these coins/projects have some good purpose of coming up with these projects, but with proper marketing strategy and different community supporters there could be some good reach. As for doge coin, it has been over the years and somehow has gained it's ground in the crypto space, but was needing supporter(s), now it has gotten one, there is room for better future with doge.
