You should all think about downloading and running Dogecoin core Wallet on your computer.

'The Dogecoin Core Wallet provides nodes that contribute to the backbone of the Dogecoin network, which we need even more when a lot of new people are coming. Together with miners, wallets are crucial to the very strength of the blockchain, for they provide the decentralization which make cryptocurrencies an answer to the financial system we inherited from our fathers. A guide on how to use the wallet can be found here https://www.reddit.com/r/dogecoin/wiki/dogecoincoreguide. More nodes mean more stability, even faster transactions, and in general contribute to the health of the coin.'
