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.
First of all, context. OP is asking about staking for profit, not about staking as a consensus mechanism.
Inflation is inflation no matter where it's coming from. Of course every newly minted bitcoin dilutes the value of other bitcoins but the demand is strong enough to maintain the price, i.e. there is value added elsewhere that outweighs the inflation rate (below 2% annual ATM).
I doubt the same can be said about whatever shitcoin the OP is peddling, or most staking shitcoins TBH. Without demand that creates value, staking "profit" - and therefore the OP's question - is useless.
