The problem is that we have not any major exchange for BTCz,, but don't worry, be patient.
In (near) future, majors exchanges will registering BTCz for free because BTCz is one of the better crypto project, with BTC.
Use donation for major improvment, test, community support (website, blog, howto, tuto, video, audio, translations...)
That's it ! Be patient, buy BTCz, mine BTCz and hold BTCz : the goal is arround 100 KSatoshis for one BTCz :-) : the same capitalisation as BTC, in a few years.
Please start a exchange listing donation fund to bring Bitcoin Z to Binnance.
I followed the project since its start.
I actually mined the coins almost immediately after its launch point.
Honestly, Bitcoin Z has big community behind, therefore I believe the donation fund (if created) will got lots of supports from generous donators.
