Two stories for that.

1. Around year 2000 during the DotCom NASDAQ bubble I happened to read about a stock higly recommended by Merryl Lynch, Verticalnet, which was around 300-400$ and Merryl Lynch predicted it would go to 600$.
A few weeks later it was 30$. So I bought it, because if Merryl Lynch had said it is good, at 30$ is was clearly a bargain.
A few weeks later it was 3$. Then 1$, And finally only a bounch of cents,
This is the regulated stock market. No thank you.

2. Bitcoin did not have a premine, but Satoshi's stake of estimated over 1 Million BTCs looks very much like an instamine, even though it took him time to mine them - ALONE. He still has those coins.
