However I think the data provided by @gavrilo77 is very interesting. Practically he made 133% of the initial capital in 833 days and he has still 55% of initial capital left. So he was making 58%/y minting with PoB, while coins decayed were 19%/y. In other words his profits were 58%/y and his losses were 19%/y. So his net profits are 39%/y. And it's not the maximum profit possible, as he hasn't kept his computer always on.
When someone invests into the real estate which he rents then, he may make let say 10%/y which seems much less than the above 39%/y, but he is able to sell his property in whatever moment, maybe making some profit as well.
When someone buys a business his profits may vary, but he can sell his business as well.
When someone invests into mining he needs to buy equipment and maybe his profits are less than 39%/y, but he is able to sell his equipment anytime.
When someone is masternoding he can sell his collateral anytime and the same with Pos.
With PoB the capital invested is lost forever.
So in order to compare Masternoding with PoB, for instance, we can say that in case of PoB the collateral is recovered in 2-3 years if we consider the 58% or 39% mentioned above and then one begins making profits, the same with PoS and PoW compared with PoB.
But in the mean time the quantity of PoB miners can increase and also the price of SLM can change, so because 2-3 years is an eternity in the cryptoworld the risks are very high compared to PoW, PoS and Masternoding and the profits are not that high to justify that high risks.
Your statements are very correct but again IF. Now imagine that all mined coins are burned or most, PoB would take over PoW and PoS. PoB Rewards would come much often. For mining you can invest in equipment, but you have to pay electricity, maybe after sometime would be failure of the equipment and you never get back your investment and depend of the price as well. With PoB is investing in equipment "worry free". PoS interest is usually small. Personal, i would rather burn huge amount of SLM and collect the rewards. For instance i am collecting with this diff around 600 SLM per day, hypothetically if all conditions are the same including BTC price, i should get a year 175 $, and that i did not move. Now again IF, if you burn 5mil SLM, you can calculate. I dont want to say you are not right but yes everything is only IF
I think I understand well your point. And I'm very interested SLM to become a success.
That's why I think we need to see things from the point of view of an investor, if we want to advertise SLM correctly.
So let's try to discern the IFs from the facts.
If we compare the profitability of SLM with the profitability of DASH we can see, that DASH's ROI is 6.34%/y right now.
While basing ourselves on @johnwhitestar's calculations and the data you kindly provided, we have agreed that the SLM's ROI is 39%/y.
But the DASH's ROI and the SLM's ROI here are different. Because in DASH you can withdraw your capital anytime while in SLM you can't so you need 2-3 years to recover the capital invested.
So if in the first year the DASH's investor has 100% of capital available + 6.34% of profit, in the same year the SLM's investor has only 39% in his hands.
In the second year the DASH's investor has still 100% of his capital in his hands + 12.68% of profit (for the first and the second year), while the SLM investor has 78% available.
In the third year the DAHS's investor has 100% of capital + 19.02% of profit, while the SLM investor has 117% of profit.
And only on the fourth year the SLM investor would surpass the DASH's investor making 156% of profit, while the DASH's investor would have available 100% of capital + 25.36% of profit.
The ROI of DASH is one of the lowest one among the other masternode's currencies and still we'd need an investor ready to invest into SLM for a very long period of time, in order his investment to be more profitable that the same investment into DASH.
The same situation with PoS. Let's compare the profitability of SLM and PPC.
In the first year the PPC investor has 100% of capital + 1% of profit, while the SLM investor has 39% of profit.
In the second year the PPC investor has 100% of capital +2% of profit, while the SLM investor has 78% of profit.
And only during the third year the SLM investor surpasses the PPC investor, as at the end of that year the SLM investor would have 117% of profit, while the PPC investor would have only 100% of capital + 3% of profit.
Of course all the above are estimates, assuming that nothing has changed in the mean time, but we doing so for the sake of clarity because we have a moral obligation to advertise SLM correctly and also because if we don't do so the investors won't invest they'll just laugh at us.
