The whitepaper is available from either https://plaza.lu (click on the hamburger top right then "Whitepaper"), or from https://www.offchain.lu.
There is a liquidity pool on TribalDex that works as often as Hive Engine works (and not more often 😄).
The order book is indeed mostly empty which reflects the fact that we miss a good salesperson (hence no "buy" orders) but all participants still believe in the project and refuse to sell OCLT (hence no sell orders).
But if you want to acquire OCLT from the Initial Token Offering you can send HIVE or HBD to @ocl-ito1 and you'll get a guaranteed amount of OCLT (currently 500 OCLT / €)
Cool, bought some on H-E - not a lot but now a partner lol :-)
