I guess the "quality" of an attorney is most important for cases that are decided by evidence and procedure. ISTM that if the feds come after you for this set of crimes it doesn't matter who your lawyer is or what you did or didn't do, you're going to be found guilty. The accused in this case can negotiate for the possession of the BTC with or without a "good" lawyer. He just needs a competent lawyer to supervise the terms of his guilty plea.
