McLSIf you can mine (my laptop would burn down...) then it can be worth it (you normally get 1000 000doge so around 400$), but don't think you'll ever get enough doge by just using faucets—1$ is around 2000dogecoins (you get around 1 to 5 doge on most faucets)...
so pretty much no way to get free $ with doge unless your parents pay for electricity and you have a beast of a computer. If you wanna buy some doge to buy useless shit with dogecoins then go for it, but pretty much bit coins without the illicit and "scary" stuff.
mining's actually suprisingly not profitable, especially since more people started using ASIC's. and faucets are just for people starting out so they can get a feel for the coin, it's not necessarily supposed to be a sustainable source of income.
(also, transactions are still secure on doge, so it can still be used for illicit stuff)
