should i mine doge coin?

Not worth it at all, it's a meme coin and will go no where.

You should know, dogecoin is a coin with an unlimited total supply. It will suffer from very high inflation because its current price is inflated by billionaire Elon Musk. If you want to invest, I think you will prefer other coins with more value like BNB, ETH, BTC, CAKE, etc.
