For example anyone can report an internet crime to the IC3, but what the FBI will do for you is another question. For now you might want to get professional legal advice from a local lawyer to explore your options first. Hiring lawyers who specialize in crypto is probably an overkill for your case because your dispute with Kraken sounds like a simple breach-of-contact issue.

Once you figure out what legal actions you'll take against Kraken, see if you can pay a paralegal (not a lawyer) to help you write a demand letter detailing the legal steps you'll take. After you send the letter to Kraken, be prepared to follow through with your actions (like hiring a lawyer) if Kraken doesn't budge. This will probably save you some money.
