I don't think you understand how startups work, nor how software development works, especially in this space (blockchain & smart contracts) which changes continuously and rapidly.
And no these are not basic signs of scam, a scam is when the team disappears or when they don't deliver a product or they just raise funds and run with the money.
None of the above applies to Etherparty:

- The team is active, they are going to conferences all over the world, they have been doing so since before the token sale and they just came back from 2 conferences in China. They also have other planned conferences.
- The team is ever growing with new employees (including devs) joining the team, just check the team page.
- EP has launched their platform a couple of weeks back, it is live, they are waiting for the first customers (out of 6 confirmed customers) to launch their crowdfund on Rocket: https://rocket.etherparty.com.
- They are also very active on all their community channels, answering questions and sharing news and updates, keeping everyone up to date.

The reason why I say you are trolling is because you are just throwing baseless accusations, and I will tackle each of your points below:

1) The team delays release:
That's normal with a startup, it's normal with big companies imagine a startup, so nothing surprising there, all blockchain projects I know of have had delays none of them delivered on time.

2) The team absolutely does not follow the promised roadmap:
There was no promise, if you read the terms of sale or whitepaper, all details are subject to change as it is normal for a startup to make new plans depending on business and market conditions for the better of the company and its supporters. No company out there will ever make a promise, not sure where you get that from. The roadmap has been changed because the scope of the project has also changed, this was announced early this year in a blogpost explaining why, check out their blog (do some research) they are delivering end-to-end products first Rocket (crowdfunds), then Hero (charity), then Saturn (supply chain). They have released a new "tentative" roadmap during one of their AMAs, also available on the blog here.

3) The team does not monitor the price of its shares:
First of all there are no shares, FUEL is a utility token that gives you access to the platform, surely you must know what you purchased before you purchased it right? The team has always been clear they are not involved with secondary markets because of regulatory concerns, many projects do pump their tokens but at the end of the day most don't have any product, while EP has actually a live product. Also they announced that EP won't be selling any tokens from the ones they hold and they are put on hold until further notice. Customers will have to source their tokens from the current circulating supply on exchanges. What does that mean? That as more customers use Rocket, demand for FUEL will increase and where do these FUEL come from? From exchanges. That is a positive development in my opinion, they also announced that once customers use FUEL on Rocket the company will also lock them for a certain period of time making supply even scarcer over time.

4) The team does shitposting, bad communication with investors:
This is your opinion, don't even know what you mean by shitposting, as I mentioned above they are very active on all their channels and answer all questions as they come, they won't answer questions about token price for obvious reasons but their admins are very proactive and you can't deny that.

5) And if the price falls from ICO -70%, it indicates the inefficiency of the company! They absolutely do not care about investors and obligations:
We are in a bear market for tokens we have had a good time towards the end of 2017 beginning of 2018 but now it's over, if you don't realize that then you are not in the loop with what's happening. Ethereum was 1500 dollars back in January it is about 450 now, is Ethereum inefficient according to your logic? Bitcoin was 20,000 dollars back in January it is now 8000 is Bitcoin inefficient? BCH was 3500 dollars, it is about 800 now, is BCH inefficient? And I can go on and on and on... You don't get it that's your problem not EPs problem. However, value of a token comes from its utilization and the product, EP has a good product and more to come which will increase the value of the token over time. I have confidence in the team, they have experience and are employing new staff all the times, surely someone is going to be smiling in a few months, especially as more companies use Rocket for their crowdfunds. One thing I learned in the space is that patience is always rewarding, of course, if you chose a good team with a great idea. In my opinion EP is one of them. And on a final note, you bought a utility token, if you want responsibility toward investors go buy shares on the stock market, don't buy tokens. I personally believe the money they have raised is being managed pretty well and quite happy they have already delivered the first product. Now I don't know many other projects that have launched a product within less than a year from their crowdfund, that is something to be thrilled about.

The rest of your comments are personal opinions that show your poor understanding of the space and even Etherparty, the company you invested in, so they are not worth replying to.
Just because you say it's a scam doesn't actually means it is, you'd be better refraining from posting such comments as anyone else is well aware of who the team is, their experience and the efforts that are going into building EP.

Give us all a favour, just have a break, be patient and you'll see things will improve over time. Personally I have no rush, I've been around a while and I know a good team when I pick my tokens. Don't take my word for it do your own research, always. By posting crap like you do you are not helping anyone, not even yourself, try to be more positive, it will go a long way.
