Is Dogecoin Worth Investing?
TL;DR Dogecoin has something in common with Bitcoin and Ethereum, like the use of Blockchain and the Proof of Work consensus algorithm. However, it is quicker than Bitcoin. It makes it easier for miners to record and complete transactions, making it easier for payment to be processed. It takes about 10 minutes for the Bitcoin blockchain to ratify new blocks. However, new blocks only take 1 minute to be ratified on the Dogecoin blockchain.
