I am a securities/crypto attorney, so I am a bit biased. However, I think the above point is correct. A knowledgeable securities attorney with experience in blockchain/crypto is certainly worth the expense. An ounce of prevention is worth a pound of cure, as they say. At the same time, having represented some 20 ICO issuers, I can tell you that from the legal professional's perspective not all clients are always telling you the truth.
