Bitcoin in cautious trading after another security breach in Japan

Bitcoin rose on Thursday for the third session with the gains still limited amid spreading caution in the market after another security breach in Japan that led to a loss of $60 million. 

At Bitstamp, Bitcoin rose $22, or 0.3% to $6,410, with an intraday high at $6,420, and a low at $6,379. 

Bitcoin rose 0.9% on Wednesday, the second profit in a row, after marking two-week lows at $6,100. 

Market value of cryptocurrencies rose a billion dollars today to $201 billion, with marginal gains in most cryptocurrencies. 

In Japan, the world's second largest crypto market, the Osaka-based Tech Bureau Corp announced its Zaif exchange suffered a loss of 6,000 bitcoins and some others in a recent hack, worth 6.7 billion yen. 

The security breach occurred on September 14, with the perpetrators stealing 4.5 billion yen from live client wallets, in addition to 2.2 billion from company assets. 

In the UK, lawmakers criticized the current state of the crypto business as "wild west", calling for tighter regulations to protect investors and prevent fraud and hacking.
