“Considering the whole industry is still in its preliminary stage, BSN has a long way to go,” Liu said. “It’s expensive to build a blockchain. Different platforms have different structures. Data are not interchangeable. Relevant projects are hard to promote. These problems have yet to be addressed by BSN.”


Last year was a big year for blockchain projects in China after President Xi Jinping called for further development of the technology at the end of 2019, but the country continues to shun cryptocurrencies like bitcoin.

Bitcoin options’ daily trading volume has crossed the $1 billion mark for the first time, as bitcoin surges past $23, 000.

Crypto exchange Deribit leads the bitcoin options market, followed by Bit.com and OKEx, according to tracker Skew. Meanwhile, bitcoin is trading hands at around $23, 550 on Coinbase, according to TradingView.

Deribit CEO John Jansen told The Block that it is “quite a special day” as all metrics have hit new all-time high records for the exchange — total open interest, total turnover, and total options turnover.

Bitcoin has been hyped as the currency of the future. And it does have its advantages, as we discussed in the previous video. However, Bitcoin is far from perfect. Because of its finite supply, there is the real possibility of “lost Bitcoins” leading to lost fortunes. These lost fortunes may lead to the erosion of public trust in Bitcoin.
