I'd say buy some more, so that all the dogecoin miners are going to mine the usde.
Yep now is the time to buy not sell. Price will go up once it hits Cryptsy
Well time will tell but now I would say selling is a great idea! It is already up. If you have a least %50 percent profit already. Just sell it, you can buy it back later once cheap.
For the ones buying above 400, I think they wont make much profit. this is my thought, no offence. Best.
No, you are totally wrong. Sometimes the price never gets back after skyrocketing. You'll be among the ones who regrets selling immaturely.
Its called buy rumor sell facts, we are at early rumor phase.
Look what happened with TIPS... was trading very low... rumor about cryptsy put the coin very high, hit cryptsy coin crashed. Same is applying here with USDe, trading at 90 last week, and jump to 550 on the cryptsy rumor, but it was not USDe that they added but TIPS, now the rumor is back. Ones USDe hit cryptsy it will have the same reaction as all of those coins. Will start high, after 1 hours it is already a lot lower. Do the maths, how much is USDe worth? $2,000,000? mmm, more then lottocoin and earthcoin, maybe, maybe not. My target price is 170 as this put us close to $2M, so currently the rumor has put USDe too expensive and i'm infact reduce my number of coins and will buy back later.
You might be right, you might be not.
But there are several facts to consider:
Our network hash rate is around 1.2 GH.
Leafcoin's block reward will be halved in 2-3 days with a network power of ~6 GH.
Dogecoin will be halved in 15 day, network with 60-90 GH.
So a few people might change their mining power towards USDE once it gets popular.
The big multipools like middlecoin, multipool.us won't be able to mine USDE without increasing the difficulty a lot.
Our coinmarketcap is around $500k, right now $2-3 million is quite possible.
And at last pr campaigns of the team and community are about to start.
Doesn't look too bad for me, if you are in for the long run.
you still can gain 100% 
I will certainly sell short at 450 and execute my short at 320.
