StartEngine only makes sense if the structure, fee load, and hold period line up with the way you are actually trying to make money.
Review the offering documents, redemption terms, portfolio concentration, and how fees work in practice.
The right question is not whether the category sounds attractive. It is whether the expected return drivers are strong enough to compensate you for the illiquidity and complexity.
How should I evaluate fees?
Look for management fees, servicing fees, performance fees, deal-level expenses, and exit-related economics. The right benchmark is net return after all fees, not headline yield alone.
What are the main risks?
Key risks include illiquidity, valuation opacity, leverage, manager execution risk, concentration, and tax complexity. The category matters, but structure and manager quality matter just as much.
Are alternative investments liquid?
Usually not in the same way as public stocks or ETFs. Many alternatives have quarterly redemption windows, secondary market limits, or multi-year lockups.
