Last week, NATO announced the launch of the Baltic Sentinel mission to oversee infrastructure security in the Baltics. The fact is that in the past two months alone, several submarine cables between Lithuania and Sweden, Germany and Finland, and Estonia and Finland have been damaged. A similar unpleasant story recently happened with Taiwan, which will now more carefully guard underwater communication cables near the island from the actions of suspicious ships. The measures are being introduced after damage was caused to a China-linked vessel by one of them. With over 95% of Internet traffic passing through undersea cables, which support $10 trillion in financial transactions every day, the world is deeply concerned about such sabotage. We contacted Professor and Chief Advisor on Scientific and Technical Policy of Ukrtelecom, Viktor Katko, who is perhaps the only expert in Ukraine specializing in the topic of submarine cables and has been studying them for over 30 years. We talked about the durability of such infrastructure, possible negative scenarios in case of its serious damage, and how Ukraine can develop the submarine network after the war.

Проте є інструмент із прогнозованою річною дохідністю від 9,5% в доларах до виплати податків і від 8,5% — після, і це цінні папери фонду Inzhur Supermarket. Інвестори отримують дохід вже в перший місяць після вкладення. Загалом за півтора року існування фонд виплатив їм майже 78 млн грн дивідендів.
