But don't forget that these tokens are still selling for more than you could buy them for during the ICO, even after the dip.

Some do implement a so-called cliff of 6 months where they can't sell. Do check my post on Status. Only 41% of all tokens will go to people contributing to the ICO.
Tezos directly ships 8.5% away to a company also owned by the founders but a separate entity.
