  • Retail access helps smaller investors participate, but it does not change the underlying odds.
  • The best platform is the one whose deal quality, diversification, and access rules fit your risk budget.

How to use this page

Read the structure before the story

Start with eligibility

Check whether the platform matches your access level and minimum before spending time on the return story.

Treat liquidity as a first-order risk

Redemption terms, gates, and hold periods often matter more in practice than the headline category.

FAQs

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.
