I would say Doge did get a large amount of adoption. I saw pictures of restaurants accepting it, a UK furniture store's online site that accepted Doge, etc. There really were/are lots of strange businesses that accept Dogecoin. The only coins I've purchased something with so far are BTC, LTC, and Doge.
I wouldn't say that all amounted to much with Doge though.
It still just ended up being a vocal minority world wide.
Look how fast & hard all that vanished when they price dropped..
The dev himself announced he quit because the community failed to support Doge coin.
BUT Doge was never launched as a currency in the first place !
The dev said it was started as a joke..
In reality it was started as a pump & dump clone.. that to his surprise took off in popularity.
THAT is the reality (
