The most important lesson of financial literacy I received at the age of 10. Guys from the neighboring area asked for a debt of 50 tenge (10 rubles), promising to pay back the next day twice as much, being a trick I could not believe in such luck and decided to invest all the assets available at the time in such a profitable enterprise, of course, my money as the guys I have never seen in my life, but remained grateful to them in the end, because meeting all new and new embodiments of the pyramids and exciting proposals from hardly familiar people to invest in a super profitable business, the same case emerges in my memory.
