Elon Musk may love Dogecoin but it doesn't mean he's the only one capable of such. Dogecoin has its own community and so has some use cases as a payment solution. So, yes, it can still pump without Musk's intervention. After all, it has doing that before Mr. Musk's intrusion
I've seen pretty good pumps from Dogecoin in 2018 and 2019. But it's not strong enough because many holders release their assets in bulk when pumping. although the dogecoin community is growing well with a very strong developing ecosystem. but we should not be ashamed to believe that the hype created by Elon is very strong. it made a huge adoption for dogecoin.
