1. If you think that the share price will stay high enough to sell at a profit after collecting dividends for a short term. While this has been possible for various timeframes in the life of TAT.VM, this is very risky speculation.
2. If you think that difficulty will stop rising at some point in the next few weeks/months. This is not the forecast, nor the consensus of the community.
3. If you think that difficulty will decrease, or continue to decrease sometime in the next year or so. This is rather unlikely, but I suppose there are some scenarios where something like this is possible, like bitcoin permanently forking, or become much less popular, etc.
In short, buying TAT.VM in the current environment, and under the current forecast, effectively means you are either betting against the difficulty rate, or speculating that the share price will hold longer than the yield % warrants.
I really respect you for explaining this openly. But the TL;DR of this is simply: You don't believe yourself that your asset will be profitable for your investors. Fun part is, investors keep buying anyway
Conclusion: Maybe only interesting for the megarich investors who want to hedge all possibilities. Everyone else stay away.
