One of the frequent complaints is how long it takes to get a new Dogecoin client up and running (unless you use a light client such as Multidoge). You can speed this process up by using the bootstrapped blockchain file, provided below.
Grab the file below, it's about 7.5GB, so you want to get started early. Once it's downloaded, you need to:
On Windows this is in your home directory, under "AppData\Roaming\DogeCoin". Easiest way of getting to the AppData directory is to open Windows Explorer and enter "%appdata%" as a path. For example, on my Windows install the file would end up as "C:\Users\rnicoll\AppData\Roaming\DogeCoin\bootstrap.dat".
On Mac, the path should be "~/Library/App Support/Dogecoin/bootstrap.dat".
On Linux, it will be "~/.dogecoin/bootstrap.dat".
Once the client has completed syncing (this will probably still take an hour or more depending on your computer), it will rename the file to "bootstrap.dat.old". You can now delete the file (probably a good idea to shut down your client before you do this, just in case).
