What the author of the topic described is not something unique or surprising. Let's be honest - which of you started working with crypto in 2017, had a financial education, studied financial and investment management? Personally, I had a basic institute courses in economics, and separate courses in entrepreneurship. I can’t say that I had the same result as the author, rather, on the contrary, I earned well, but ... I didn’t manage to fix everything and turn it into liquid things. I only managed to buy ... what I planned to buy for the last 2-3 years, and set aside a certain amount as a "financial pillow". It took about 50% of what I earned in 2017. And the second 50% of what we managed to earn eventually turned into ... about 5% -10%
No, this is also money, but - not received or, more correctly, profit that was not fixed IN TIME, turned out to be quite significant. This was an excellent lesson, and prompted to study more deeply similar assets, the investment market and speculation. Once again I was convinced that a negative experience is the most useful and memorable!
I recommend everyone to study the subject matter, read specialized materials, communicate on topics of interest, and constantly develop. This will be the key to a secure and quality life not only for you, but also for your families.
