New to Doge,
What Doge really offering? besides all the funny hype of the dog.
Is there any long-term benefit (staking maybe?)
Dogecoin is PoW coin which means that it releyes on mining same as bitcoin, it is not PoS aka proof of stake that allows staking. Basically it is ordinary coin with infinite supply (there is not a cap like bitcoin), faster blocks and cheap fees. It has big comunity and they tend not to be only in there to make money but I see that their community is doing some work for charities and trying to help around as they can to promote the cryptocurrency and dogecoin. Also seems like that devs are back and are looking forward to release new version this year - in future they even might adopt SegWit.
I think that they done something to prevent this by having AuxPow aka merged mining with litecoin, but I don't really know technical details in full about this topic.
