If you consider attending a conference in Switzerland, most likely it will be in English. Therefore, you would need an on-site Russian interpreter. Whether you are in Geneva, Zurich or anywhere in Switzerland, English is spoken in all cantons. The blockchain conference attracted those who have startups in blockchain technologies and also investors from various countries. I have assisted a group of Russian bankers in exploring the best jurisdiction for the Crypto company.
As a part of this assignment, I encountered some new blockchain-related terms in English. For example, asset tokenization, which is in the Russian language токенизация активов.
