I guess this question has not been asked here or somewhere on this forum as I have searched for this to no avail.
I ask this because I expect to receive around 1,000 dogecoins (wish it were Bitcoin though) into my paper wallet this weekend.
How much really can a Paper Wallet Hold?
there is no limit, a paper wallet usually just shows your (wif compressed) private key and your address (which is basically a hash of your private key).
you can create as much transactions whose outputs can be spent by the owner of the address, you can theoretically send all DOGE ever mined (minus the coinbase in the very first block) to your paper wallet without consequences (besides the doge market would probably collapse if you were the only one holding DOGE)
