That guide is a beast, and it even has how to use the 500 address staking technique.

Is this a parody?
What kind of pinhead would stake a 6% coin which is basically a rounding error in crypto?
So the 500 address thing "increases staking" but no further information? What fun.
If so, then this is a straight up scam in the DNR code and needs to be exposed.
Splitting your coins in a wallet increases the amount of matured transactions that are available to stake - so more stake blocks will be generated. The only advantage to this is as a result of creating more stake blocks, you collect transaction fees for each blocks. The increase is absolutely minimal and does not create any extra PoS income - the total generated amount is still 6% of the staked coins - if you only had 100 coins, you might increase your profit by a few percent just be adding transaction fees over the course of a year's worth of stake blocks.
It may be worth mentioning, the technique works on any PoS coin, it's not something specific to Denarius.
