Bitcoin (BTC) has seen solid growth, having surpassed the $6,600 price point, starting the day just over $6,400. The leading cryptocurrency is up around 3 percent over the past 24 hours, trading at $6,624 at press time.

August 22 Bitcoin plunged from above $6,700 to under the $6,400 price point, following news of new anti-crypto policies in China, as well as another series of application denials for several Bitcoin exchange-traded funds (ETFs) by the U.S. Securities and Exchange Commission (SEC).

According to CoinMarketCap, Bitcoin and VeChain (VET) are the only two cryptocurrencies among top 20 coins by market cap that have seen some gains over the past 7 days, with Bitcoin up just 1.43 percent.

Among the top 10 coins, EOS (EOS) and Monero (XMR) have seen the most significant growth over the past 24 hours, up 4.7 and 3.9 percent respectively.

Today’s solid upswing in the crypto markets comes following an announcement from the U.S. SEC that the Commission will review its August 22 decision to reject nine applications for listing Bitcoin ETFs.

Earlier today, CNBC's crypto market analyst Brian Kelly predicted that the first Bitcoin ETFs will start operating in February 2019. According to Kelly, the world is getting “incrementally closer” to the first Bitcoin ETF approval, pointing at the bullish “sentiment change,” despite the recent application rejections.
