PoS would be a bad move imo... which is probably what they will go to haha
DoGE went perfect to start and ever since near Christmas it has been exact opposite of what I wanted to see.
I am working on something for doge people to speculate on with DOGE rather than just btc/doge or ltc!

I love lil doge for whatever reason
Hope all is well Lynn.
Why would it be a bad move? It would improve security since Doge is well distributed, and it would solve the inflation problem since it would be equally redistributed to everyone. By merge-mining with LTC, the big inflation rate could still be a problem.
What will we be able to speculate on?

Hope all is well for you too!
Proof of Share would be a horrible move for Doge, I think.
Well distributed? you're kidding, right?
http://bitinfocharts.com/top-100-richest-dogecoin-addresses.html32.68% of all coins are in only 6 address. 46.15% of coins are in only 66 addresses... Doge could get 51% stake attacked so easily under PoS.
AuxPoW is the only viable option right now, and as the Doge hashrate and blockreward continues to decline, the community is rapidly losing the opportunity to get mining pools to add merge-mining.
Why would the 6 owner of these adresses, who most likely are exchanges with no contact to each other, want to colaborate to destroy the coin when they hold such a huge amount of it?
You have a fair point, but I think PoS is considerably better than the current system. I'm not totally against auxPoW either, but I don't trust LTC to maintain an high value for a long enough time to make it truly worthwhile to fork to be merge-minable with them.
