DOGE is just a meme coin and hype because of Elon Musk, in my opinion it's better for you to invest in Ethereum than DOGE, because it's safer and definitely gives you profit, so you don't need to hesitate or be afraid to invest in Ethereum and of course the project from Ethereum is very good and popular.
Actually, Dogecoin is good as a memecoin, it's just being romanticized by Elon and many traders and scalpers that like to have quick profits.
When it was not yet that popular because of Elon, it's living good and the community really likes it.
We have preferences in investing in the market, I like ETH and I'll agree to you but you'll see people that will dislike that suggestion of yours because they have doge and it's possible that they've bought it while it's on its peak price.
