Doge to the moon y'all! Sold all mine years ago but it's good to see everyone doing well.
I had to look up my mistake in 2019.... I been transferring coins from the now Defunk Thecoin.pw exchange. I sent 13,000 Doge to what I thought was my wallet... Well just before I had transferred DGB to its wallet and when I copied what I thought was my Doge wallet it still had the DGB address. (Big Mistake) At that time 13k doge was worth $80. today its worth $4600! I still monitor that address cause I am curious, some day someone will or might get that address and have a nice surprise! Makes me cry to think what it will be worth someday though....
Do you have access to your Digibyte private key? I don't know how compatible Doge and Digibyte addresses are, but I would try importing your Digibyte private key into Dogecoin QT.
If the addresses are compatible (very good chance since both start with letter D, and both are forks of Litecoin), you might be able to use the private key to derive the same address.
If you can't recover it, well, take solace in the fact that you probably would have sold it way before the current upsurge in price like many of us did. Because let's be realistic, not many people thought Doge would reach the price it is at today.
