I am a new host to Airbnb, offering an upscale townhouse for long-term rental. Almost immediately I received an inquiry from a Chinese gentleman who wanted to book my place for a long-term period. However, he did not want to use the platform, only WhatsApp to communicate. Also, he wanted to pay in cash, professing that he made his money in cryptocurrency. It took me a few days to realize that he is a scammer. Not sure what he is scamming, however. Can someone explain what's going on. BTW, I did contact Airbnb, who removed him from the platform. Scary.
