Bitcoin's rollercoaster year has taken a sharp downturn once again. On Tuesday, the world's largest cryptocurrency slipped under £79,000 ($100,000) for the first time since June, as renewed fears over the US government shutdown and slowing global growth sparked widespread selling.
Once hailed as an unstoppable juggernaut after soaring past £99,000 ($126,000) in early October, Bitcoin has now lost nearly 20% of its value in under a month.
