An example being that say I have a 1,000,000 coins of x currency and the percent a year is 5. Regardless of the stake age, if I leave the wallet alone and stake as normal, difficulty willing, I will only be able to receive approximately 5 percent of what I have, in this case 50,000, by year's end. As in, it's in the wallet code to make sure I will not be able to cross the 5 percent of my total staked savings? Or is the percent a year merely the amount that will be awarded to me for each staked block? Such as, your stake reward will be in the amount of 5 percent a year of the coins the staked block contained and is not the maximum a year that can be earned. So if I am staking a coin that is not being widely staked at the moment or is relatively new I could reasonably surpass the 5 percent a year staking?
Thank you in advance.
The annual PoS interest is always without a compounding effect. So it can be a lot more if you don't remove your PoS rewards from your wallet after staking.
And even this is a guesstimate, there are many other variables that can increase/decrease that percentage. For example, Magicoin has a higher % when the net weight is higher.
I don't know of any coins that have a built-in hard limit, but there's no need of that with a proper PoS implementation ^^
My thinking process was, is maintaining a certain network weight similar to having mining equipment of a certain speed? Depending on how much you invest and on what coin you can "mine" more if you are willing to maintain a certain weight (or hashrate in my) the APY would be the block reward. So I was wondering if the interest was fixed or the expected reward per stake.
