Its up to them since many people want to earn more money from trading rather than holding, personally, when I see an opportunity to trade then I will trade all my funds without any leverage. But when the market is hard to decide, holding my funds while staking is preferable.
Of course when they are responsible for what they decide then they are free to do anything for their own interests.
I don't trade, but I tend to invest long term. The profit I get can be no more than the traders, or it can be better than most novice traders, but the point is this has to be done as needed. So it's definitely not a problem to get them to trade, invest or whatever they think is better. It really depends, but all in all the goal is profit.
