I can summarize the scams in two categories: asian vs white, latina, black.
White, latina, and black ask for giftcards, money over the wire and etc.
Asians like Chinese, Japanese, and Korean will ask you to be an investor for crypto currency and get involve in MT 5 trading.
They will want you to set up.an account and deposit your own money to play at the MT 5 platform.
If you want to initiate a relationship with them, they will avoid your initiation at all costs. They just want your money to be deposited in their brokerage account having power over your hard earned currency...
