Ponzi schemes are illegal and so long as bitcoin remains a vehicle entirely for speculation, it's sorta-kinda-almost a ponzi scheme.
Quite a few ICOs and altcoins certainly were created with the intent of such a scheme and should definitely be considered illegal.
In reality, intent matters, and since bitcoin was not created with the intent of creating a pyramid, it seems likely it should be legal, at least by that particular possible illegality.
