This came from a dating app in USA where a girl claims to be doing very well trading crypto using a "P2P" platform with "time nodes" and she sent me this URL to download an app for my phone to trade USDT/BTC etc. using her "strategies". I am pretty sure it is a scam but the girl seems pretty normal otherwise and has pics with her family and friends that seem real.
You are being catfished OP. I very much doubt those pictures are real unless they're dumb enough to reveal themselves. Look up romance scams and you'll find the same stories. You can try to drop their pictures in reverse image search engines (google, bing, tineye, yandex, etc.) but do note that if it doesn't return any results, it doesn't mean they are what they claim to be. It's just some scammers use photos which are wide spread all over the internet.
If any stranger starts talking about money, you should immediately run... almost everytime they don't end well. Take note that some of these scammers are a bit tricky. They would spend a good amount of time (weeks, months...) to make you warm up to them before they start talking about finances and stuff, and therefore to some people, it comes off as natural or less alarming at least.
Lastly, limit the personal information you give out to ppl you don't know well, particularly those that could reveal your financial situation cause scammers could use it to assess if you're worth the trouble.
