Bitcoin's so-called halving event has had little impact on its price so far, with industry insiders on Monday saying the cryptocurrency's fortunes were more closely tied to broader financial market sentiment and geopolitics. Bitcoin enthusiasts had eagerly waited for the "halving" - a change to the cryptocurrency's underlying technology that happened around 0014 GMT on Saturday and is designed to cut the rate at which new bitcoins are created. By 1415 GMT on Monday, there was little discernible impact, with bitcoin trading at $66,300.
