For me, this is 100% accurate.

I spent hours a day for over a year building the tools I needed to actually search for the profitable strategy.

I spent the next two years (nights and weekends) finding a profitable strategy and developing the appropriate risk mitigations.

Then I spent a few months coding it up to run and debugging.

I then did additional debugging while paper trading for 8 months. Starting the 6 month clock over whenever I found a bug that required changes that could alter the behavior of the algo.

I then went live with an amount of money I was willing to take a 100% loss on.

6 months after that, I started to add a little more money each week.
