If you invested $100K in Microsoft (one of the safest and most valuable and boring company in the world at the time) in 2017 and held, you’d not be a multimillionaire, but you’d be a millionaire. People really underestimate how crazy the asset bubble has been over the last decade.
USD 100k is an absurd amount for most people to invest all at once in anything whatsoever, not to mention the risk level involved. USD 10k is a lot but more reasonable. And that nets way less than USD 100k in this situation, which isn't life changing.
