◢Hitters Present at the Blockchain Meetup of The Economist China Readers Club

On January 13th, Nebulas founder Hitters Xu was invited as one of the panelists at the blockchain meetup of Economist China Readers Club and shared his insights in the future of blockchain with many industry influencers. Other panelists included the Managing Director of the Economist Global Business Review Wu Chen, Gingko CEO & President Zuo Peng and Co-founder of HQ Finance Ni Yabo.

The two panels of this meetup addresses two of the most-discussed topics: whether the year of 2018 will see the massive application of the blockchain technology, and how to understand the current blockchain bubble.

In terms of the first question, Hitters Xu believes that the application of any technology is a gradual process. The mass application of the blockchain technology is always a quantitative change resulting from accumulated qualitative change. What’s more, Hitters pointed out that people seem to have misunderstandings about the “killer app” of blockchain in that they think it must bring value to traditional industries as a tool. However, Hitters believes that public chain represents a fundamentally different way of thinking.

“Ask not what blockchain can do for you, ask what you can do for blockchain.”

Hitters also expressed his concern of the bubble in the blockchain industry. He said the bubble is reminiscent of the dot-com around 2000.

“If the bubble begins to burst before the blockchain technology makes any substantial breakthroughs, it will be a devastating to the industry. So it is of great importance that blockchain technology makes technological breakthroughs before the bubble bursts down.”
