Here is the way I look at it. At the Beginning of the DOT COM Boom people were snatching up every name they could come up with that sounded cool or was easy to remember. Now that Crypto Coins have come on the scene we have the ability to start projects that are backed up entirely by the Communities holding the Crypto Coin in Question.

For example the DOGECOIN Community is probably one of the fastest and biggest growing communities in the Crypto Scene. And they started with a JOKE and MEME of a popular Dog.

Its not just the various use cases that give these coins value its the fact that the community involved with said coins or ICO's are willing to accept them in exchange for physical products are services much the same way we use FIAT Currency and Bank Credit today.
