I’ve randomly come across a trader on LinkedIn proposing account management services and get weekly payment back from initial investment, such as $500 get you $1500, $2000 yields $6000 weekly and so on.
Real and professional traders are too busy managing their portfolios so I doubt they really have time on that account management service. And there is no trader, no matter how professional they are, can give you an assurance that they can give you a
"guaranteed weekly payment" with that kind of numbers. Crypto is heavily volatile and always remember that.
It smells too good to be true, but at the same time I have zero knowledge about trading, except that it does exist and some people do make money from it.
Sounds that you are considering taking the bait since you have zero knowledge in trading. Always trust your ability to smell rubbish offers on the web.
So far he proposed to open an account on Coinmama and go from there.

Common scams
New scams appear all the time, and nobody has the full list. Having said that, here are some of the more known scams that are currently terrorizing the cryptocurrency industry:
Account managers and brokers. Pretending to keep your interests at heart, these so-called account managers, investment bankers and brokers will obtain your details and, after a while, abuse it. Make sure you've done your research before letting someone manage your crypto assets for you.
Airbnb. If someone is asking you to pay an Airbnb rent or deposit in crypto, you're being scammed. Airbnb does not support crypto payments
Amazon. If you're trying to cancel your Amazon Prime or get a refund, know that Amazon will never ask for your card details over the phone, and also does not support crypto payments
