If I’m a KOL, I’ll open 100 media accounts: 50疯狂唱多 and 50疯狂唱空. The 50 that are correct go into group A1; the incorrect 50 go into group B1.

For the next prediction, the A1 group keeps 25疯狂唱多 and 25疯狂唱空, and the 25 that are wrong get deleted.

The B1 group also continues with 25疯狂唱多 and 25疯狂唱空; the 25 that are correct get deleted.

For the next prediction, follow the same process above.

That way, you’ll end up with two premium accounts:
One that accurately calls every market move—legendary.
The other that precisely goes against the trend—and it can also generate huge traffic.

Then you can start charging.
