This website has a wealth of content on how to avoid internet scams.
If you do not have time to read all of it, at least keep in mind the following points:
Be skeptical of too good to be true offers.
Other than to a legitimate financial institution, never pay money in order to receive money later.
If you are anyone other than a heterosexual man looking for a heterosexual woman, there is a very significant chance that someone on the internet claiming to seek a social or outright romantic relationship with you will be a scammer.
If you are a heterosexual man, there is an absolutely overwhelming chance that someone on the internet claiming to be a heterosexual woman seeking a social or outright romantic relationship with you will be a scammer.
Regardless of your gender and the gender of any person who you wish to socialize with, if someone online tries to convince you to purchase either:
Gift cards
Cryptocurrency
you would be extremely well served by assuming that it is a scam.
Bonus Material
Assume that you are a man who is either:
considering buying a product and/or service or
in the process of buying a product and/or service.
The saleswoman starts to act flirtatiously.
What does that mean?
It means that the saleswoman is attempting to maximize her chance of selling you a product and/or service.
Summary
If a bombshell at the sales desk at a gym convinces you to buy 5 consecutive lifetime gym memberships, at least you'll get to use the first one.
If a person on the internet sends you a photo of a buxom light-skinned East Asian woman and he or she then suggests that you "invest" in a fake cryptocurrency exchange, you get nothing. Note that I intentionally list both the pronoun "he" and the "pronoun" she. Regardless of whether a cryptocurrency scammer is a man using the photo of a woman or whether there is video of an actual woman who is every bit as live as the saleswoman at the gym, the person or persons promoting a cryptocurrency scam are still scammers.
This year, and in all the years to come, people will continue to lose large amounts of money because they chose to ignore the guidance on this web page.
