Exactly that is what I though. Even though Doge has reached decent heights in the past, it was mostly because of it's community.
Doge supporters were everywhere. Where are they right now?
What technical features does DOGE offer to compete with other coins, or future coins? None.
I also doubt that Doge will ever reach $1 Billion, $100M is what I'm questioning as well.
Doge's community is primarily active on reddit and IRC.
In terms of features, 1 minute block times meaning a fraction of the time to first confirmation and an inflationary economic model used to mitigate transaction costs and encourage spending. AuxPoW removes the conflict with Litecoin for Scrypt hashrate, which is the single biggest hurdle for Dogecoin right now.
