To put it mildly, 99% of KOLs in the secondary market basically started with small market caps.

Yes, but it's not replicable.

Small market caps are not a guaranteed win; they can get delisted, experience severe drops, and have endless lateral movements. The valuation changes greatly in different market conditions. If it doesn't torment you to the brink, there won't be explosive gains.

However, the win rate is indeed high.

The only help that paid groups provide is to help you discover truly valuable coins. But whether you can get rich quickly still depends on your luck.
