Equity investments are inherently high risk, so if you can afford to lose your entire investment and can wait 7-10 years for a return, then the answer could be yes.

You might strongly believe in a company's future success, but it's safer to think of an equity investment as a lottery ticket that might pay off in the long term.

Unlike the stock market, investment outcomes are much more binary (complete failure or wild success). No stock market allows you to easily re-sell your investment stake to someone else unless the company is acquired or prepares for an IPO.
