Yes, recently there has been a surge of interest in the Diamonds. 

If this coin is still alive, why she does not have your web site?

then you need to secure the return of coins on http://www.coinwarz.com/ that people could see the state of the network and Profitability of production.

To start, let's make  website  for coino, and we'll see ..

this conclusion is based on all the events that happened to this coin.
In any case, wishing to revive this coin, have to work hard. So far the only coin that has managed to recover from the departure of the old developers, this Diamond. They even managed to change the algorithm that would help protect networks from Asik mainers. Perhaps that coino have to do the same.

You can assume that the coin is now completely free from his old owners and waiting  new comers to give it attention.

old developers will always find a reason for which they are forced to leave. In fact, everything is much easier, they create a new coin, and is profitable for them than to maintain the old one and then create another. This unfortunate trend will continue as long as new investors will not stop and are not be buying new artificially inflated coins, do understand that they are being deceived.

Hi. when will the new wallet with an updated logo and appearance? 

about what hope do you say? In the world of crypto currency in any major owner coino must not only investors, but also contribute to the promotion. Otherwise he will be with a bunch of useless coins. Who is stopping you, if you are such an investor - create a website, hire a developer for a new purse, pay for advertising. What's the problem?
developers who originally created coino, already long gone, earning money at the start and now create new coins, trying to just slip them on the exchange. with each new coin their chance of success will be less. but that's another history.

Need as soon as possible to release a new wallet with a new code that would use the old purses became impossible, and it would make it impossible job of old wallets.

I think what is important now is not to find out ip address of the attacker, the more so that there will be a chain of proxy servers. Main fix the vulnerability resolve this and do that in the future this would not happen again.

There is still a lot of work to strengthen the security of the network of Diamond and prevent such attacks in the future. Such methods are available and should be used .. The Diamond should be one of the most stable coins to such attacks. Only then will success.

Maybe just someone checks the network Diamond strength, because even half a year ago a lot of coins were split (ftc, trc, and others) some unknown with large computing power.

People still do not understand the advantage of fast coins.. Many in the public does not know about crypto currency. Now the market is in chaos and puppeteers speculators conduct their dirty games. The technical characteristics of coino has an advantage over many, artificially inflated coins. But at the initial stage, it is necessary to create a normal website. this is the first step to revival coino.

I see that the DMD community is a on the right track, We need more shops and services receiving payment in Diamond

I know of several major news items devoted crypto currency.
1. www.coindesk.com/news/
2. www.cryptocoinsnews.com/
3. crypto-news.com/
4. www.cryptoarticles.com/
But I have no personal contact with the owners.

Happy birthday to the entire community, now we need a good Diamond promotion.

Of course, what kind of growth rates is now possible to say when the only major market for Diamond is cryptsy, but they are or does not understand or does not want to update the information ..
The main task is now to develop the infrastructure and make the most accessible for any user and technical information about Diamonds.
Until the autumn much more time, but still worth it to get a move on this issue ..

May already be enough produce useless and empty coin?
I understand that greed and boundless desire to get rich quickly driven many developers, to quickly create a blank coins, but how many more people need to cheat, that they would have realized this and stopped buying pacifiers.

Look here for an example http://www.worldcoinexplorer.com/Explorer/RichList

In normal browsers blocks explorer has such an option. Unfortunately the current explorer Diamond has no such option...
