Cryptosphere is not well regulated yet. Do you know any cryptoexchanges which works under any legislation?
Or at least are there any steps towards this regulation?
There are Japanese exchanges in the market that are licensed and regulated under the regulating authority of Japan. But I am not sure about any other exchanges which are actively regulated by any government regulatory authority. Majority of the exchanges are registered but that certainly doesn't mean regulated.
However, recently SEC has floated out a circular which says every Cryptocurrency exchanges must be registered and regulated as per their regulatory norms if they want to conduct business from their country. Check the link below,
