If you're looking for something serious, choose Bitcoin or Ethereum instead. Who knows how long will the "meme" coins craze last? 
Not only did it last but its flourishing now more than ever
this is largely thanks to Elon's interest but also because it has some technical merit, which other memecoins are famously devoid of.Dogecoin has surprised everyone and more especially those who called it a shitcoin some years ago. Elon's interest in it is what I do not understand, what is his reason for supporting dogecoin instead of bitcoin everyone is killing themselves for. Do you know or is it so that bitcoin lovers can get envious?
