Dogecoin (DOGE) transaction fee history up until October 25, 2021

Between December 2020 and January 2021, the fee for a transaction involving Dogecoin increased by over 1,500 percent. Transaction fees refer to the money paid to the cryptocurrency's miners to get transactions accepted, and cost increases can occur when user numbers increase: as the blockchain has limited space available to process all the transactions, it effectively becomes congested. Growing transaction fees therefore represent both the number of Dogecoin transactions that are waiting in line to be processed, but are also meant as an incentive to miners to process the especially large transactions - as they are more profitable for them. The increase in fees for the cryptocurrrency coincide with both an increase in Dogecoin transactions as well as a price surge for Dogecoin after tweets from Tesla CEO Elon Musk in early 2021.
