I had a bunch of Doge too but I simply mined it back in 2013. I sold it at some point when all the markets crashed early 2014, and turned it all into btc and ltc so I didn't have to bother with a ton of wallets. And besides, Dogecoin.. never expected it to survive this long, let alone thrive.
I have always thought Dogecoin should be picked up and continued development on, and perhaps turn it into a children's cryptocurrency. It's super cheap and even kids can own hundreds. It would educate and raise an entire generation on crypto and teach them all about it. I learned about crypto through Dogecoin too, because it was so cheap that it didn't matter if I made a mistake!
