This doesn't strike me as lawsuit-worthy at all. First, you have not really articulated a legal claim. Second, your damages are difficult to prove and speculative at best.

Third, in crypto-finance there ought to be a strong presumption against litigating using "first realm" courts. Absent some intentional misconduct or fraud, people should work these things out on their own. Your options are (1) be careful whom you deal with, either know them personally or get references whom you trust, so that you will not be surprised by behavior that you should have expected; (2) for transactions where you must deal with an unknown counter-party, arrange for escrow by a mutually trusted person. This is how it's done.
