I haven't been following Waves as close as I used to, but I think that Poloniex was given the possibility to run a full node when the tokens were released, eg same time frame as Bittrex started trading. For whatever reasons, they have not chosen to have Waves trading on their system. In general every exchange would of course want to run their own nodes to audit and verify the code, and to enable accounts for all users for their backend.

when to release?

Use the latest version of Waves clients: Lite client (v0.4.1) Chrome App (0.4.1a) + Tutorials

But (To withdraw) From Bittrex to Lite wallet - Remove(1Wfrom_your_address)

There are some news? Please share with us.

As soon as the news will be available, I will post it here.

Yes, actually the developers are doing a testing of the nodes for a long time and yes, this thread available for those who will start testing a code when the node will be available.

Please feel free to report about possible bugs when code will be available

I think ICOs should never start with a moderated thread.

I am in the boat of no thread on bitcointalk should be moderated. ICO especially. Just take the good with the bad, people are easy to ignore when they are as stupid as the majority of haters around here. Laugh and move on, if you cannot laugh then you are taking yourself/investment to seriously.

In the next few days, first of all will be the public testing.
