Choosing a broker, investment firm

Assalamu Alaykom,

I’m just learning finance, so please excuse the simplicity of my question.

I just bought my first crypto and I’m interested in investing with a broker, investment firm called pyramid profits
technically, you give them money, they invest it using an Automated trading system, and give you percentage of your money (profit) every day…

I’m still hesitant about starting with them, as I don’t know yet the (Halal - Haram) part of it…
My Questions are:

1- can you please advise me on the right questions to ask before starting with a broker to make sure it’s Halal investment?

2 - is my choice regarding this particular firm right? as I’m leaning towards them at the moment?
