I used to mine Doge back in 2016ish and used to hold quite a bit of it. Quite honestly I believe Doge is still only a meme coin and is unbelievably overvalued, but we'll see what happens. If you're looking at investing into Doge remember to never invest what you can't afford to lose and that the Crypto market is essentially entirely unregulated. Pump and dump schemes are incredibly common, especially with coins like Dogecoin.
