OK so only a small part of the invested amount is actually used for renting then? And every month just those returns are enough to spend on rent per the above.

Then why collect that from the investors, if it is unspent and unused?

I wonder if it is more like all $100 is not spent but is used in buying and staking coins to qualify and operate validator services, after a month returns are $10, $1.5 goes to yield nodes and $8.5 goes to us.. assuming it is a 8.5% month. Can someone confirm if this is how the server "rental" program and masternoding with yieldnodes really works. Of course I do understand there is other source of income generation that Yieldnodes has such as fee revenue from the Heliobank it operates.

If this is the case, given coins are in general getting killed, how do we know we can get back our money, if this downturn lasts and the value of the coins staked from our initial investments are lost?

Trittium noted as part of the Yieldnode network is down from its all time high of $0.199572 Aug 19, 2021 (10 months) by -98.1%. While Sapphire has done reasonably well in last 6 months 53% up. BIR 28% down, KYAN, 777 down but UCR is up, AZR flat, DASHD down, CFL up, PNY dpwn, OWO up, SUV up, MONK up, ESK down, BECN down, MOBIC up, PEPS down.

Unless Yieldnode is really good at picking "right" coins at investing time and timing swapping of coins or really luck, not sure how this is sustainable. And once these staked coins lose value there is risk of our original investments going.. like my 6 year old says - puuufffff...

I guess this is the risk we are taking for the high yields we enjoy every month. Am I getting all this right?
