Please help me see if this is a scam

Here is the website to invest in https://theminingstate.com/.

I can't tell if this is a scam. My sister is investing in this and her BF already has been using this for months and is apparently getting a payout.

Essentially you help a company buy a miner and he pays you out for the amount he gets back.

I have no idea how to make this 500 characters it keeps getting flagged. So sorry there is fluff. I just want to know if I should invest in this company as well. it seems legit. He takes money through PayPal. I'm a super noob in crypto, but it seems like a legit investment. Her BF has been doing this and has been receiving a payout. How is it possible to get scammed from this?
