So I commented on the lettuce hand hahahahha go outside sardines

Here’s a clearer and more polished version of your text:

I invest $300 per month when the price is $0.30. When it reaches $0.60, I increase my investment to $600 per month. If the price drops to $0.10, I reduce my investment to $200 per month. I keep repeating this strategy over and over. But one day, I’ll probably only invest $1 per month — FET just doesn’t interest me anymore.

Would you like me to make it sound more professional or more casual/personal?
