Paying $2000 to join for coaching and selling their products

I have my mindset set on paying a high-value membership and I'm pretty much convinced I will have a positive ROI after a while.
Now, this is a lot of money and the risk of getting fucked seams minimal.
Have done some research to see if the company have a bad rep but I couldn't find anything.

What measures would you take beforehand in case you got ripped off and the money goes bye-bye and you get nothing in return.

Appreciate your response

BTW Would you inform your CC number through a chat?
