If you have no another plan, why not? But if you gonna sell BTC or other promising cryptos for Dogecoins, think about it. It doesn't worth selling BTC and buy dogecoin which is promoted by social media influencers.
I agree, it is very unprofitable in my opinion if we want to sell bitcoin just because we want to buy Dogecoin, I don't see Dogecoin as having a decent value when compared to bitcoin, the history of Dogecoin is proof that if indeed Dogecoin is a meme coin, there are many other coins that are better than dogecoin, like ethereum or binance coin.
The increase in the price of Dogecoin in the last few weeks is not because Dogecoin has good fundamentals, but because it was pump up by Elon Musk and his followers who spread the FOMO.
