Visionary leaders, economic pioneers and enterprising investors from around the world will come together for one of the most exclusive events on the global blockchain calendar.

As the longest-running crypto-technology conference in Dubai, WBF will delve into the innovative possibilities of blockchain technology, the impact of cryptocurrencies on global financial markets and the shifting landscape of ICOs.
