Hi,
i'm holding my ZEITs from day one. And waiting and waiting and nothings happens. Sure u made some small progress with ULI, but why you don't do some big project? First of all you should make new website, more attractive for investors and after you should consider about making some portal to give ZEIT some useful value that will also raise demand on the market.
For example you can do some portal where users can trade their knowledge for time (ZEIT).
Short example:
I'm developer, you hire me to make you a website. I need 72 hours to make you an website so I trade my time with you for website and get payed in ZEIT. You can also made some ERC20 subtoken for portal and you can automate things with smart contracts, then users can swap this subtokens for ZEIT and get interest from POS.
