Truong Tan, 30, in Hanoi, said he has been using Tinder for three years and has learned a lesson from using the dating app.

“I had been using Tinder for two years when I was cheated, and I was not a rookie at all,” he said, referring to how he lost VND3 million to a girl who said that she was a person from a good family in Ha dong district.

After a period of communicating and meeting, the girl revealed that she was unhappy because her ex-boyfriend cruelly treated her, and the parents were too harsh.

When they became close friends, the girl asked Tan to help her pay for goods and borrowed money from Tan, promising that she would pay the money back as soon as she could.

“She repaid VND2 million after many times of breaking her promise. But she still owes me VND3 million, and she never appears before me,” Tan said, adding that VND3 million is the "tuition" he paid for the lesson he received from Tinder.

After Tan posted his story on several groups, his story got a lot of comments from those who were cheated by the same girl. Tan realized that when she met him, she was pregnant and married.

Do Son from Hanoi told VietNamNet that he was cheated by a girl that he had never met. When Son sent a message and asked her to make acquaintance, the girl, who said she was born in 2022, said she was busy for an advertising shoot in Ha Giang.

“She said the weather conditions in Ha Giang were severe, so she caught a fever while filming and she needed money to buy medicine. Some days later, she once again said she wanted to borrow money to buy some errands. And I remitted money to her bank account,” Son recalled.

However, when the girl said she wanted to borrow VND1 million, Son did not have VND1 million to lend. When the girl came back to Hanoi and Son wanted to meet her, the girl said she would not meet him unless she could borrow VND1 million.

“She reproached me when I said I didn’t have money to lend. When I asked for my money back, she unfriended with me,” he said, adding that he felt lucky as the amount  he lost was not that much.

Meanwhile, Nha Van in HCM City has warned about temptations to invest in cryptocurrency.

“This guy looked handsome, polite and knowledgeable about financial investment. He said he had a furniture company in Hong Kong (China). He even won my trust by saying that he had an unhappy childhood - his parents divorced and he had to live with his grandmother. I burst into tears when I heard the story,” Van recalled.

After one week of flirting and making video calls, he began talking about how he could earn much money from investments in cryptocurrency. He even showed his account, saying that he could earn VND60-70 million a day. He said he would be willing to help Van learn about investment. The starting investment level was $500.

When Van refused to make an investment, the man disappeared.

Later, when Van related the story to her friends, she realized that many other girls had fallen into the man’s trap. A girl agreed to make investment with $100, but later she discovered that she was cheated. The man then created a virtual nickname and threatened to reveal all the secrets she confided to him to her friends and family.

According to Nha Van, in most cases, scammers begin mentioning an investment or borrowing money after a period of making acquaintance, because after becoming close friends, people will be no longer cautious about friends and easily fall into traps.

According to a survey by Decision Lab, 65 percent of 1,012 Vietnamese who were polled were using at least one dating app. Tinder is the most popular app, used by 22 percent of people. The other popular apps include Zalo and Telegram (21 percent) and Facebook Dating (17 percent).
