There is something called the "gun test". The crypto on an encrypted hard drive is not more secure than the gold bars in a locked safe. Its security is a function of how the secret holder response to gun-on-their-head events. In this case, since the government is directly involved (and angry), a lot of criminals may pick personal safety over assets.
Frankly, I think a large portion of cryptocurrency proponents are overly confident in its "decentralization" and "safety". Cryptocurrency is only as safe as gold bars in a locked safe; and worse if you use a public exchange.
