I think there are several different strategies for earning profits with MSS and MoonYield (jury is still out on Book of Binance), but sustainability is still an issue with all 3 in my opinion.

Here's the thing I find unmanageable for the MSS ROI dApp: Start with $100 worth of MSS, and in under a year (349 days), if prices remain stable then you have a $100k account. In the meantime you are trying to outrun the price degradation. But, if they continue the incentives to keep the price afloat this benefits mostly huge MSS accounts.

If you follow the MSS Youtubers you'll soon start to see 3M+ MSS accounts. Some have multiple accounts. A 1% Claim is worth $541.50.

MoonYield is an attempt to create a system for users to hold their MSS vs sell it, dropping the price. But, every so often a whale just decides to sell mass quantities of MSS, MUSD and/or MoonShare, kneecapping the price. So, it's another one of those row with the group and you will fail, act like making money is the point of this game, and you will likely win, destroying the project in the process.

I'm still figuring this whole system out, along with investor actions in the face of mass hyperinflation. I do like the dev, and think he is doing his best to try to retain value, but it may turn into what I typically see in these dashboard money projects: a cascade of projects/protocols that try to stem the bleeding price from hypercompounding/hyperinflation, but ultimately fail.

So yeah, still evaluating it, but have slowed down writing about the ecosystem until I see some daylight in the hyperinflation problem.
