Years required to become an expert forex trader

For any expert trader reading this how many years of trading did it take you to become an expert trader. Just to be clear I define expert as someone who has a win rate of 80%.

You can have a win rate with less 40%and haveca positive balance …depends on some facts and doing your numbers …
To become and expert 80 %…come on that not the parameter
Depends on your time and your effort …i know some one didi it within 1 year

If anyone on the planet has a 80% win rate consistently for years, they are a time traveller.

What you should be asking is how many profitable years would an expert experienced trader expect, and how long did it take him/her to reach that success level?

I’ve known scalping traders make profits on the 1 minute TF with less than 5% win ratio.
How?
Trading different pairs, they will close losing trades immediately, and run winning pairs
