You're right, but wouldn't it be ~80% of 51% (or ~40%)?
I'm referencing the whitepaper from my phone, so it's not easy to double check.
No, the remaining 49% are tokens, that were not for sale. 20% went to the team (they cannot sell it for a year), and 29% was meant to be a backup for future projects, however they can sell it right away if they havent got enough money to buy a property.
