How did they want to scam me?

Three weeks ago I got a message from supposedly a Malaysian girl. She was supposedly trying to reach a guide in my city, because she was wanted to travel to my country, to my city. In the first hour she asked me to text her in her other ‘’travel” number. We messaged for a bit, I told about my city, what to do during the stay and so on. She said she travels alot cause she has her own business and investments so no need for her to work much. What I found interesting is that she always wrote ,,good morning,, around 11:00-11:30, mostly talked about weather and mostly ended her sentences with ,,dear,, (typical google translate bullshit). Only three weeks later she mentioned how she makes her money from crypto and that I can also do the same by downloading crypto.com defi wallet, buying 35 USDT to “active mining node certificate miner” so I can make 1% daily gains. I had my suspicions from the start, but kept messaging to see where it goes. Knowing that they invested 3 weeks into this its not about 35$, but probably later investments. My question would be how would they scam me in this scenario after I transfer 35$? Is there anything close to the daily gains of 1% while participating in nodes or staking?
