Even though dogecoin was created just for fun, the dogecoin has managed to remain fairly valuable over the last seven years.
at this time what you say can be true and we can not cover the situation, but will it continue also there are still many conclusions that will occur.
Created for fun is a marketing gimmick. Doge was created as a scam. But very soon they decided to add big enough tail emission so they make that scam premine irrelevant. Doge is just a normal coin. Just like Bitcoin, Litecoin and 1000 others. Copying Bitcoin. Nothing fun, nothing meme nothing, ... A working transparent ledger coin with known issues that such coins have.
I actually see what you say is an undeniable necessity, that it could be that their marketing / sales have done something for purposes that we don't know.
For me, it is strange that people like @elomusk have joined the coin doge issue, with the statement.
doge really is no different from other coins and we will wait for the continuation of the doge story which is quite phenomenal at this time.
