Now the volume looks increased at exchanges, I think people have started to buy more bitcoins, and because of that the value of bitcoin started to increase, and in turn peoples interest will be increased more
yes after crossing the 600$ there is a little increase in the volume of bitcoin, in previous days the price of bitcoin become so slow because of the bifinex issue, that really effect the price of bitcoin, people were not taking interest in and just try to continue safe mood.
Current market show a promising bullish , and people start interested to go invest again.
Some rumours say that bitfinex hack is the reason people prefer to hold a little amount bitcoin in the third party such as exchange.
But I don't think it is affected too much to bitcoin volume, it is might because people just keep holding without keep buying at this point?
