Tezos is still under development and coins can be bought at few exchanges.
From what I see it ethereum's competitor and new platform for smart contracts and dap's. It is still under testing, but developers are very active and it can become big project.
Disclamer - i don't hold any tezos.
Tezos has applied KYC verification to the all of their investors. You could try to tell someone does he still remember his password because in fact that there is a lot of people are loosing it right now.
For hudreds millions blockchain and this is a very worst project but it's not so bad as 4 billion blockchain with so many buggy code.
