As part of a clampdown on bitcoin in China, the nation's bitcoin exchanges were forced by the authorities to pull out of any official involvement with Beijing's Global Bitcoin Summit earlier this month.
Both OKCoin's Star Xu and Huobi's Leon Li are optimistic about bitcoin's future in China, they said, and see the current regulatory environment as a real, but temporary problem that can be overcome.
The CEOs also addressed the Chinese central bank's concerns regarding excessive price speculation and investor risk, hinting that this may be driving the government's recent actions and agreeing that exchanges could do more to curb such activity.
Star Xu, OKCoin
Xu first got into bitcoin at the beginning of 2012, he said, after seeing the digital currency mentioned on an episode of TV drama series The Good Wife, he said. After falling in love with the concept and researching the topic further, he began trading on Mt. Gox and BTC China later that year. He founded OKCoin early in 2013.
"I felt that they could do better," he said. "So I wanted to found a new exchange."
Finding investors that also believed in digital currency was the key, he said:
Xu advises other startup owners to be prepared to run their business for two years as they looked for investors.
"It's really important to get the right investors for the right startup," he said. "They should match beautifully."
Bitcoin startups need to move more slowly, he continued, because they needed to help their customers better understand bitcoin and the risks associated with its use.
Banks and regulation
Despite the recent regulatory environment in China, Xu said that he still thought his native country was less restrictive than others, which have also seen bank account closures and even arrests of bitcoin exchange operators:
The People's Bank of China's policies would "bring a period of hardship", but, in the long term, the situation would improve, he predicted, since the government has shown some interest in communicating with bitcoin companies.
Xu's ultimate goal is to take OKCoin international in some form, either directly or by licensing the company's technology to other companies:
"We can make more and more customers love bitcoin, and use bitcoin,: he added. "The important thing for all of us, is that bitcoin has no nationality."
Mt. Gox revival?
Under the plan, the exchange would not launch a direct takeover, but assemble a new team leveraging OKCoin's technology and experience, and make an application to the Japanese bankruptcy court overseeing the case.
Xu became interested in reviving Mt. Gox after one of his friends suggested OKCoin could help out with its technology and experience, he said. Trying to resurrect the business and return funds to its customers was important for the whole bitcoin community, he added.
Only the court could decide in the end, he pointed out, so his team would have to apply to the Japanese bankruptcy court and await its reply:
Leon Li, Huobi
Like Xu, Huobi CEO Leon Li is positive about the future of bitcoin in China, in several sectors. There is a lot of trading and mining activity in China, he told CoinDesk, but the surrounding services, like apps and APIs, need improvement.
Speculation on bitcoin price had been "too hot" in the past year, and China's exchanges needed to calm things down, he argued. Many investors were looking to make short-term gains, he said, and that kind of activity needed to be kept in check "for the good of the country".
As for the near future in the wake of new central bank restrictions, Huobi said it had a two-stage plan to continue business.
The first step will be to move away from direct interaction with the banks and instead interact with a "peer-to-peer network", in which Huobi would function as a platform for users to trade fiat currency for bitcoins directly with each other.
The second step will be to investigate opportunities overseas, although Li did not specify at this stage what those opportunities might be.
