Maybe some context would help with the question, what risks are you interested in or just in general?
Regarding deeds risk can be minimised by owning a certain proportion of each deed type. As before when the CLD price dropped the AUD price jumped up, so owning some of both balances the loses. It is like backing every horse in the race.
Of course to do this it might mean increasing your overall investment in EU which has intrinsic risk which can't really be reduced.
In terms of hunting/mining/crafting, go easy and be sensible seems to be the lowest risk route. Try always on quantity rather than condition, avoid amps and mobs above your level. Team hunting also reduces the risk by allowing you to be part of more mob kills and increases the chance of a nice multiplier.
