According to foreign media reports, the price of encrypted digital currencies continued to rise generally on Wednesday, and further rose after bottoming out yesterday. Among them, the price of Bitcoin rose by nearly 8%, returning to above $8,000.

CoinDesk data shows that the price of Bitcoin hit a high of $8,582.93 during the day. CoinDesk tracks the prices of cryptocurrencies such as Bitstamp, Coinbase, itBit and Bitfinex.

According to data provided by CoinMarketCap, a cryptocurrency data analysis website, as of 4 p.m. Eastern Time on Friday (5 a.m. Beijing Time on Saturday), the price of Bitcoin rose 7.61% to $8,195.15.

At the same time, the price of Bitcoin futures for delivery in February on the Chicago Mercantile Exchange (CME) rose by $640 to $8,190, an increase of 8.48%, after hitting a high of $8,540.

Among other cryptocurrencies, Ethereum rose 7.43% to $826.54; Ripple rose 3.36% to $0.77; Bitcoin Cash rose 6.59% to $1,011.47; and Litecoin rose 6.69% to $149.97.

One of the reasons for the rise in cryptocurrencies is that at a hearing on virtual currencies held by the U.S. Senate Banking Committee on Tuesday, U.S. Securities and Exchange Commission (SEC) Chairman Jay Clayton and U.S. Commodity Futures Trading Commission (CFTC) Chairman Christopher Giancarlo emphasized consumer protection issues but did not propose a strict ban on the development of cryptocurrencies.

In addition, the two senior regulators also said that U.S. Treasury Secretary Steven Mnuchin is bringing together multiple federal government agencies to coordinate regulation of this rapidly growing industry.

Before the hearing, bitcoin prices fell below $6,000, hitting a low of $5,947.40, the lowest price since November 13 last year. At the same time, U.S. stocks also fell sharply. The S&P 500 closed up 1.7% on Tuesday, but it has still fallen more than 4% since the stock market began to sell off last Friday.

After the recent broad-based heavy selling in the cryptocurrency market, some experts said the market could see a bigger bull run this year than last year, with its total market value perhaps breaking the $1 trillion mark.

"Growing regulatory recognition of cryptocurrency exchanges, the entry of institutional capital, and significant technological developments will contribute to the market's rebound and push cryptocurrency prices to new highs this year," Thomas Glucksmann, head of business development for Asia Pacific (APAC) at cryptocurrency exchange Gatecoin, wrote in an email to CNBC on Tuesday. "There is no reason to think that the price of Bitcoin won't push to $50,000." Jamie Burke, CEO of blockchain-focused venture capital firm Outlier Ventures, also wrote in an email to CNBC on Tuesday: "We believe that after February, the market is likely to usher in a bull run that will be at least as large as last year, possibly bringing the total market value to $1 trillion, and then the cryptocurrency market will enter a proper 'winter' period when the market will focus more on its fundamentals."
