The share of bitcoin traded this weekend has fallen to an all-time low of 16 per cent, according to Kaiko, a cryptocurrency research firm. The fall follows the launch of a spot bitcoin ETF, which appears to have changed the schedule of bitcoin trading to more align with that of traditional bourse and reduce bitcoin price volatility. Cryptocurrences, unlike stocks, can be traded 24/7, even on Saturdays and Sundays. In the past, bitcoin trading was notorious for its "crazy weekends", but this phenomenon appears to be cooling as bitcoin weekend trading volumes have continued to decline from their 2019 highs of 28%. The launch of bitcoin ETFs may be a big reason for this. Dessislava Aubert, senior analyst at Kaiko, said the decline in weekend trading was "a trend that has been going on for years, but ETFs have exacerbated it." Kaiko said the share of bitcoins traded between 3pm and 4pm on weekdays rose to 6.7 per cent from 4.5 per cent in the fourth quarter of 2023, a period known as the benchmark pricing window during which ETF owners set the price of bitcoins and then use it to calculate the ETF's net asset value.
