We are a Collective of Citizens who are working for a better Colombia outside politics we want the orange economy applied from the future social society, we are a community that takes every day stronger and we will achieve social empowerment #scolcoin

Current "bad performance", as you called it, makes future more profitable. Einsteinium is a heavily undervalued coin. If you look at the charts, every possible sign of accumulation is there. Which brings me to "non-reaction". Actually, there were more "reactions" from the team in previous couple weeks, than in the previous couple months. It's just that people are eager for more news, because of price drop lately. They want to know what should they expect in the future.
I am convinced that price will go up (significantly), therefore I am not concerned about the project. The only thing that concerns me is that community doesn't "shoot itself to the leg" again, like they did with sill rumors, back in December. I hope EMC2 team learned their lesson, and they won't provide them ammunition again. 

The forum is a little quiet on this on. I threw a small amount at it because of the project. We'll see...

People were crazy to sell their houses when BCC didn't crash. But anyone selling their houses now to get into BCC, LOL! I don't know what to say about them

In short: Cryptonite is the only truly scalable crypto currency out there.

Reasons:
1. Fixed size blockchain -> does NOT grow forever, can be capped at any size you like.
2. Secure 0-confirmation transactions thanks to withdrawal limits -> INSTANT transactions possible.
3. Auto-adjusting block size -> Theoretically unlimited transactions/s.

NO other coin out there claims to have this combination of features and stays true to the decentralized & open source philosophy of the original Bitcoin. If we take e.g. DASH. They do instant transactions but haven't solved the growing blockchain problem AND need to manage special "trusted" nodes to achieve this.

Please correct me if there is a coin that does it better - I haven't heard of it yet.

The only thing Crpytonite hasn't implemented yet is perfect privacy like e.g. Monero. But we have ideas for how to achieve that, too.

That's why I believe in it. If there's one coin that has the potential to become a real-world payment system, it's Cryptonite.
Granted, other coins are far ahead of us with respect to publicity & marketing but I believe that no matter the situation, in the long run the product with the most solid foundation will end up as the winner. No matter how good the marketing, if the technology is flawed, it will bring a project down sooner or later. Best example is Bitcoin itself. Set off as a replacement for world-wide currency, it is severely struggling to fulfill that role, despite its unbelieveable publicity and resources.

Some Problems:
1, As a side project I am willing to put effort in the revival of this cryptocurrency? I can not understand this sentence well? XSTC's historical story is how
2, XSTC allocation rules is how? Just mine it?
3, whether there is a clear line of marketing of some projects or technology updates?

It's pretty sure that we won't be listed on Binance or Bittrex in a foreseeable future. Here is a link to our listing strategy https://medium.com/@HEROCoin/insights-on-heros-listing-strategy-da00ea10c1cf
We are working hard for additional listings and we will let you know as soon as we know something reliable.

Nova Exchange isn't shutting down, nice just read their announcement. SYNC is on 2 exchanges so this is good.

ETN is climbing....

Maybe because the mobile mining beta is live

or maybe because it's gonna be listed on hitBTC (http://bitcoinist.com/hitbtc-announces-electroneum-listing/)
