REUTERS/Neil Hall A bloodbath gripped the crypto markets this week, with virtually every single major cryptocurrency taking significant losses, but huge amounts of excitement remains about the space from all corners of society.

Bitcoin, the first, biggest, and most recognisable cryptocurrency, has been at the heart of much of that excitement, with acolytes touting it as the future of global finance, and some even suggesting that it could replace fiat currencies like the dollar and the pound.

Bitcoin's rise has been so rapid and so aggressive that the market's more established institutions and figures have been simply unable to ignore it.

There is a big spread of opinion across the sector, with some seeing cryptocurrencies as a possible driver of a fundamental shift in the global financial system, others disliking bitcoin, but having some faith in the blockchain technology that underlines it, and others just seeing crypto as, basically, a complete waste of time.
