Viktor Mazur is a financier by education, working in various sectors of the Ukrainian economy. Back in the mid-90s of the last century he began to write articles on historical and economic topics. Analyzing the socio-economic events in the life of the average Ukrainian, he began to gather information about abuses in society, which eventually became material for his books on fraud and ways to protect yourself and your wallet from scammers. He still considers the words of the French writer of the XIX century Edmond Goncourt to be topical: "What is happening today is not yet an influx of barbarians, it is an influx of charlatans." This book contains specific advice and recommendations on how to behave a decent citizen in a given situation, getting a job, in particular abroad, or when buying a tourist voucher and travel to other countries. The author exposes numerous scams in trade, including on the World Wide Web. Fraud threatens everyone - both buyers and sellers. The observations and conclusions included in the publication will be useful to everyone, because anyone can fall victim to scams and scams. In fact, someone else's experience is always better than one's own mistakes. At the end of the book there is a section in which the author talks about famous swindlers of the past.
