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)

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.
