at least in the countries they have been banned for the time being the business is over unless the get regulated
but they may! like FTX and others who knows I am just pointing out there are issues with them with many regulators...others also BITMEX all regulate din tin pot jurisdictions but it futile talking to you .. you are die hard fan it seems . simple logic is people are prepared to take market risk even the volatility of the Bitcoin but a trader / investor does not sign up for exchange itself going out of business...! + the hanging questions is what is a security and what is not ! There are many exchanges venues regulated by CFTC so why these companies shy away form it is a mystery.. it seems they don't want any scrutiny ...
