Шест поредни месеца на спадове. Рекорд. А март най-после затвори на зелено. Видяхме ли дъното? На фона на геополитическо напрежение, несигурност и пазар, който дълго време изглеждаше изтощен, Bitcoin все пак завърши март нагоре. Дали това е знак, че дъното вече е зад нас? Или просто кратка пауза преди следващото движение? На следващия Sofia Crypto Meetup ще се фокусираме основно върху Bitcoin и големия въпрос: Видяхме ли вече най-ниските нива в този цикъл? Ще обсъдим: Какво означават шестте поредни месеца на спад и защо март е толкова важен сигнал за пазара? Кои други проекти имат шанс не просто да целеят, а да излязат по-силни от този период? Фокусът ще бъде върху това кои сигнали наистина имат значение и кои проекти могат да преминат през трудния период с реални шансове за следващия етап на пазара. Без излишен шум, без магически прогнози, само добър разговор, смислен анализ и достатъчно време за въпроси и дискусия. Елате, за да обсъдим дъното заедно... И за да можете един ден да кажете: I survived the bottom!

## **Fashion and Nigeria** **What can Europe learn from Nigerian culture and fashion?** *** Fashion designer and personal stylist **Boryana Vatova** traveled to Nigeria in 2018 and stayed there until 2020. The reason – an invitation to teach fashion at the *Learn and Work* academy, where she later became Head of the Design Department. Boryana shares: *"When I moved to Nigeria, I realized how different the culture is from the European one. At first, it was difficult for me to find the right way to communicate. That’s when I started studying human nature more deeply and understood that if you approach people with genuine interest and respect, cultural differences become a bridge rather than a barrier. Gradually, I built a very strong connection with my students and the people there. They accepted me deeply and authentically, which was a great gift for me. Nigeria taught me to notice the small things, to be grateful, and to value human connection above all else."* On April 26th, we invite you to a first-hand story with both professional and personal perspectives. Through many photos, videos, and engaging stories, we will explore the following topics: • The *Learn and Work* Academy and the educational model between Italy and Nigeria • The students – their ambition and attitude toward knowledge and fashion • Nigerian fashion energy – colors, silhouettes, textiles, symbolism • Cultural identity as the foundation of style • How elements of African aesthetics can be integrated into the European fashion context The idea is to show that cultural exchange is not one-way – it is a dialogue. At the end of the talk, you will have the opportunity to ask your questions to Boryana Vatova about her experience in Nigeria, its culture, and of course – her work in fashion. 📅 **Date:** April 29, 2026 ⏰ **Time:** 20:30 – 22:30 🍷 A complimentary drink is included in a cozy atmosphere. 🎟️ **Participation fee:** €15 Please contact us to reserve your spot. 📍 **Location:** AfriKaya Studio, Lozenets district, 56–58 Krum Popov St., 3rd floor *** **More about Boryana Vatova:** My name is Boryana Vatova and I am a fashion designer and personal stylist. Between 2018 and 2020, I lived and worked in Nigeria, where I taught fashion at the private *Learn and Work* academy – an institution based on an Italian-Nigerian partnership. I later became Head of the Design Department. This experience changed not only my professional path but also the way I communicate and build relationships with people. Nigeria taught me gratitude for the small things and deep respect for cultural identity. Today, this is reflected in my work – I build strong personal connections with the people I work with and believe that fashion is a bridge between cultures. 🌐 Website: [Boryana Vatova Official Website](https://www.boriannavatova.com/?utm_source=chatgpt.com)
