Staking doesn't produce anything of value, it's just useless inflation. For every "free" coin you get by staking your portfolio is depreciating by a similar amount (or more, if some other bagholders have masternodes or some other contraption that produces more inflation).
This is wrong on so many levels imo. Is bitcoin mining also useless inflation with no value added? Does uour Bitcoin holding depreciate every 10 minutes when a block is mined? Obviously not. Staking/Masternodes are just a form of mining with a different consensus of course.
Back to the question, if you don't trade/ don't know how to and you are just holding cryptoasset, it's best to stake. Otherwise, trading will always be more profitable. My 2 sats.
