ELI5: What makes bitcoin so valuable if anyone can create a cryptocurrency (Dogecoin for example)
gpt
It's valuable for the same reason anything is valuable.  And any random cyrptocurrency isn't valuable because of that same reason.

Things have value because people are willing to exchange it for other things of value.

If no one anywhere is willing to exchange stuff for your new cryptocurrency then it has no value.

If people are willing to give you dollars for your cryptocurrency or stuff for it, then it has value.

Bitcoin can be exchanged for dollars easily enough, your brand new cryptocurrency can't be exchanged for dollars, so it doesn't have value.
