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." It is hardly possible to find a person who has never been deceived. Another thing is that we often ask for it ourselves, and then complain about how it could have happened ... Perhaps we should remind ourselves once again: whoever is warned, is armed. The information contained in this book will help to avoid the cunning traps of swindlers to those people who believe that love can not be the subject of speculation, who trust medicine is the most valuable thing - health and for whom the car is a helper. It is on these outspoken feelings that marital swindlers, dishonest doctors and pharmacists, car insurers, dishonest drivers and other road thieves play. The author also turns to the scams of the past, trying to understand the psychology of fraudsters of different times and peoples.
