No it wouldn't happen, 90% is too big.
Maybe 50% is more realistic, Elon musk will protect this coin and dogecoin has a big community so 90% it wouldnt happen.
Even though we're in market correction doge only drop 30-35%.
Yesterday dogecoin price reached below $0.22, so it can happen anytime. Doge price still showing good movement for the shilling of Elon Musk. He makes tweet about dogecoin after every few days gap. But how long he can manipulate doge price! Dogecoin don't have bigger community like bitcoin. The price manipulation of doge won't last forever. At that point we will experience a quick drop of doge price.
This project will soon dump as expected and no shitcoins that could stay longer in the hype, not even Doge. If I invest in this coin, I won't hesitate to sell it now while the price is so hot and it is in the prime stage. We can't consider this coin for long-term holding, a fully manipulated project like Doge has nothing to rely on it and selling is the smartest way than missing it.
Anyway, we all have a different price prediction, some manage to hold it and looking for x10, well, that's their choice. And if he fails, nobody else to blame, right?
