It's a tradition in dogecoin to pump and dump that garbage near the end/beginning of the year. The creator of that blockchain admitted it was just a meme and it pumps to about 1-2 cents every year before falling back to 2/10ths of a cent per dogecoin. I looked on Binance and the peak price I found was 8.7(!) cents per doge. Now it's at 2.7 cents per doge and plummeting still. Don't fall for the hype, boyos.
