Thank you very much for the comment, @rebeccabe!

I can only add that I tested it, checked, and observed it for some time. 😉
I only wouldn't agree that any type of cryptocurrency has that extra compound interest possibility. The majority of them work in a way - you buy them, and then you wait that they raise in value (if they raise).

Here, as first, you don't have to buy anything! - Huge difference!
Second, my essential math calculation (for reaching the goal of $150K in 4 years from now) is based on current Steem price (without any possible growth of the coin value). Only that already makes a huge difference in comparison with other currencies, as well as with other paying platforms available out there.

All of that even more, if the price of STEEM coin goes up (what very likely would), the earning outcome (presented in my scenario) may be much bigger or even mind blowing. Just as an example I said $1 million if one Steem reaches the value of $10.
But what if it reaches $20, $40 or even $100. Quite possibly if you take a look at Litecoin or even Ethereum, both of which are not backed by the community or even less with the platform like this one is. Where would they be if they are? 😉
Besides, STEEM is much younger coin than any of those two are. That also counts! 🙂
