This weekend, the Bitcoin (BTC) logo lit up the starry sky in Berlin and decorated the tallest building in Germany with a very large orange B.

On January 21, the symbol of Bitcoin shone on the Fern Situm Tower in Berlin, which is actually the radio and television tower. German Bitcoin customers share lighting lamp pictures and videos on Twitter and social platforms, and then shared by the famous Bitcoin Twitter account.

The person behind B, a German Bitcoin merchant named Tilo, told CoinTelegram why he had such an idea:

"We just want to attract attention on Bitcoin! We are all fans of guerrilla behavior and will continue to move forward."

Tilo is the CEO of a theme event agency, which will hold the "Best Blockchain Technology" conference this year. He explained that the whole process of setting the lighting effect display was very simple: "What you want is a switching valve, power plant and special Bitcoin logo," in a comment. Tiro tried this process at the end of last year. "But the light I used is too weak," he explained

This is not the first time that the Bitcoin logo or theme style has been projected onto a landmark building. In May 2021, in London, "Fiat car is foam plastic, and Bitcoin is paper clip" is predicted to the Bank of England.

Tillo had previously posted a Bitcoin slogan on the landmark Berlin wall and shared a product list for those interested in trying to get along with lighting fixtures. However, he insisted that such "advertising" was technically prohibited, so it was better to act cautiously.

Although the Reddit working group of Bitcoin in Germany used a series of comments "Noice" to celebrate the event, Berlin residents subreddit implemented various ways. One commentator accused light of "photochemical pollution", while another expected "it (Bitcoin) will never be fashionable." They added:

"Bitcoin is a kind of unlimited and moral and legal turbocharged bourgeoisie, which will dress up as different types of concealment and life maxims every six months."

The price of Bitcoin has gradually skyrocketed from the middle and late teens, and has remained at the 20000 dollar range, while the network information security has recently reached a record high. The hash rate, that is, the retrieval frequency of Bitcoin mining per second, has recently increased to 300 Exaash per second.

In addition, the number of Bitcoin users in the world has exceeded one million, and developed countries are beginning to pay attention to and adopt Bitcoin's blockchain technology and territorial sovereign assets. In Beijing, Germany, Berliners can use Bitcoin to pay for sandwiches at subway stations according to the lightning network.
