I think no mater what wall we setup NOW it will collapse just make some maths.
All we now that many users are mnig for profit so guys like middlecoin ext...
They mine a lot and they sell. I see that  Difficulty has big variety. Net jumps from 20 GHs to 30 GHs.

We are mining about ~500 000x60x24 Daily with current price 0,000 000 56 That gives value about ~400 BTC / day
And there is only 25 BTC mined in 10mins... So in mid-long term don't expect BooM.
Guys from multipools won't keep long their coins they pay daily income in BTC that mean price will fall no mater what we will do at this stage.
Everyday is sold out about ~100M (Only on Cryptsy) that mean we need 54 BTC every day investments.
While i am writing that wall is about 44 BTC only.
In short therm price would go down even about ~20-30 Statoshi we produce a way more that market can handle at this point but in the future who knows...
I think price will go up easy at low prices big investors will buy many coins then they can go and open some cools stuff
new markets and social services DOGE have enourmus marketing pottencial this is Crypto on top it aims in young internet user
but when that young people will grow up they will use allso Doge because they use to use it that is the best part.
In long therm Doge from other crypt alts have enormous marketing potential people like read about it, people like joke from it
people want see it succeed (maybe not other alts devs and owners).
