Eh? That's for the fools using money from others betting in unrealistic scenarios (ie, always bull), leverage, margin traders, futures, etc. When its your own money you don't care and you are not forced to do anything.

In the future you will see, who laughs last. If the USD collapses... You'll see it sooner.
