Crypto shilling can be a gray area when it comes to legality. While promoting a cryptocurrency or project isn't inherently illegal, certain actions can cross the line:

- *Securities fraud*: If a promoter makes false or misleading statements to manipulate prices or convince people to invest, it can be considered securities fraud.

- *Unregistered securities offerings*: If a promoter is paid to tout a security without proper registration, it can be illegal.

- *Insider trading*: If a promoter has access to non-public information and trades on it, it's illegal.

However, not all crypto shilling is illegal. If a promoter:

- Clearly discloses their affiliation with the project

- Doesn't make false or misleading statements

- Isn't paid to promote a security without proper registration

then it may be considered legal.

_Always do your own research and consult with a legal expert if unsure!_
