This information that I got from bitsend thread, indeed the problem of delisted from the exchange is the reason for all this. But I don't see any updates or developments that will trigger bitsend bounce back again.
Currently joshafest is working on the next version. After that we are planning an Insight Explorer and an Electrum Wallet.
Please note that my account has been blocked several times and I have to hold back to write a lot of messages.
I firmly believe in our projects but unfortunately the market is very dynamic and the elimination of cryptopia, coinexchange and bittrex were very tough steps.
As with any open source project, any participation is also possible with Bitsend.
Best Regards Christian
