This is money laundry scheme, they need "drops" who will be the ones that law enforcement will catch and who will serve time in prison.

So, congrats, you just became part of criminal scheme and got cops on your tail. Does that seemingly easy money worth of having criminal charges and black mark on your future?
Is it was so hard to google for a bit longer?
Just how this scheme works.
1)Some criminal gang use extortion, often they use indecent pictures of minors and blackmail minor to buy gift cards, so criminals wont spread his/her picture on internet. They will keep milking minor, until he report to police.
2)That dude on instagram who is likely sitting between many layers of VPN, find fools(you, if you trusted them) who will cash out these dirty cards on his name.
3)They receive goods and sell them, this is how they get "clean money" and how money laundry works.
Next step:
4)Minor or his parents will report to police and will give serial numbers of cards, which was "cashed out" and traceable to YOU by Amazon.
5)You will tell police "someone hired you", but all you have is chat with that dude, who is behind VPN, so instagram account is not traceable.
Also police can easily lie that you just faked this chat and you are criminal who extorted minor with indecent pics, and they have undeniable trace, gift cards that he purchased and you used them to buy goods. It will be hard to prove otherwise without good lawyer. Good lawyer will cost you way more than you earned from this shit.
Notice also, person offer you payments in form that is (again) not traceable, whoosh/WU doesnt really verify sender ID well, usdt/driver - i wont even comment. You are last traceable point in this criminal chain and you are the one will serve sentence.
So... lawyer up.
