That doesn't necessarily follow. If you have a billion dollars worth of BTC, you could calculate what that's worth in CLAM and declare that as your "offsite" investment. It doesn't matter that there aren't enough CLAMs in the world to actually convert it to CLAMs, it's still part of your effective bankroll, which you want to risk 1% of. The "offsite investment" feature allows you to effectively use your BTC in the JD bankroll without having to even convert it to CLAM.
