After China’s nationwide crackdown on cryptocurrency exchanges and initial coin offerings (ICOs) in late 2017, the Huobi Group shifted its headquarters from Beijing to Singapore. Now, despite the declining prices of cryptocurrencies in 2018, Huobi appears to be moving forward aggressively with its expansion efforts.
Make sense for them to moved to Singapore because its crypto friendly. I think top exchanges have a plan B, just like Binance and OKex moving to Malta.
So I'm not surprise by their move, I wouldn't call it aggressive though, perhaps its a business decision on their end to shift their HQ to a more friendly nation like Singapore so that they can still operate without any pressure from the government.
