It has started to dump.
Those influencers that have told their communities to buy dogecoin probably are enjoying the profits.
It will likely to happen, but Dogecoin will stay on and maybe another application like this will push the price of Dogecoin again, and you are right for every pump there are influencers and whales that's going to profit, but it's still good to hodl Dogecoin but another pump is unlikely.
Not likely but it did actually already.
The push for Dogecoin can be rinse and repeat by another influential social media person or a known crypto person.
