I am left to wonder, though some investors with SFR's are doing it successfully, is the risk too high for the reward?

In my mind, the liability and possibility of harming the seller outweigh the rewards.  

Though I would caution you on hard money lending until you understand the industry a bit better, that can be very rewarding but you have to be able to do your due diligence on deals because you're turning over your hard-earned money to an individuals project, often a flip. 

While rehabs can be rewarding, I’ve often ended up paying much more than I anticipated or would have liked—especially when managing from afar.

I love talking with investors, sharing values, discussing their wants and needs, helping them fully understand what they’re investing in and helping them achieve their passive income goals is very rewarding.

If I have to go through all that I should have the reward myself not give it over for 10000 +1000 !!!

Crypto is a volatile asset, but the rewards are magnitudes higher than any other traditional investment.

During period of low interest every post on BP was about cash flow - now that cash flow upon acquisition is dead the only option is equity which is also reeling because price appreciation is finally back to realitypersonally I buy for growth because I buy to hold for 10-20 years or longer.

Patience and discipline reaps its rewards. 

In the long run it will stabilize, but energy cost to reward gap is getting closer, faster.Good point about controlling the exchange rate, I'll look more into thatIf by wealth you mean cash reserves, this is regulated by government.
