but i did make profits on investing in Doge..
Good for you.
Seems like many Bitcoiners are just jealous, that Doge is currently a better investment.
Doge can go to $10 and bitcoin can reach $1 million, everyone should just accept it and enjoy success for both coins.
Bitcoin or Doge are equally profitable, it's just that what the OP means is why coins that were originally just jokes are so valuable nowadays just because of Elon musk's tweets. The thing that is feared is that in the future Elon will mess up again and make coins that previously had no price become very valuable.
