YouTube has reinstated hundreds of crypto-currency related channels after admitting it had removed them "in error".

Axar.az reports citing BBC.

A wave of YouTubers received notifications that their videos were in breach of the platform's terms of service earlier this week.

The move appeared to target smaller channels and publishers that focused on Bitcoin and crypto-currency content.

The Google-owned video sharing platform has since apologised for the mistake.

But some crypto-bloggers have complained that their videos have not been restored after several days.

"This is a huge wake up call, and I'm researching decentralised alternatives," said Chris Dunn, who has more than 200,000 subscribers on YouTube.

Video-makers initially took to Twitter to share their frustration, after many well-established channels claimed that YouTube had been ignoring their complaints.
