Hi there!
What about the listing on exchange? Is this ever going to happen?

Of course! You can take a look at the funds involved in investing in Blockstack, this will clear up a lot for you!

In December, participants were given vouchers, which will be redeemed in Q3 Q4. However, team can add you to the waitlist if you reach out to support@blockstack.com and provide your email address and legal name. Perhaps there will be another round of vouchers.

I am glad to meet you here, Mike.

The fact that the project team consists of high-class professionals, and the project was selected venture investors with well-known names, adds confidence in the success of the project in the long term, only alarming that the documentation Blockstack not enough information about the expenditure of funds collected by the ICO.

Hi Khomyak! I'm glad to see you too, join! 

Head on over to App.co to try the Universal Wallet App Finalists
Blockstack, in partnership with ShapeShift, put out a $50,000 challenge to developers around the world to create a Universal Wallet where users hold or add their favorite cryptocurrency and exchange into any token they want, all from within a wallet they privately own.
We gave teams two months to build and were impressed with the results!
The finalists are all open source and are listed in the wallet category on App.co. Note that they are all in alpha and were created in a short period of time, so you may experience a hiccup or two.
Hope you enjoy!

I should support this project because I see a good potential on it. Goodluck to the developers of this project. A successful project with an excellent idea, a world that is necessary and great potential! I am confident that the company has a great future and great prospects
