There is an option to obtain BTCs (a fraction) if you owned BTCs back then.
AFAIK it is still not certain whether this is legally possible, and whether the judge will approve of it.
It's also doubtful if the prices you claim will be those. For instance, I remember some $150 trading into MtGox back then...
IIRC this detail is defined in the latest documents. However, it is still not clear how Kobayashi will decide whether the claims are valid. He has until Sep/2015 to figure those things out.
