With so many cases, there have been many cryptocurrency exchanges that seems to be active but on the contrary, they are dead, that is, they are no longer active. Talking about the case of 6x .com, it is a cryptocurrency Exchange launched about three years ago but to my greatest suprised, it has closed.
Although, they are still available descriptions of its platform I got from my research. 6x .com aimed to be a very secure and trusted Exchange for trading with cryptocurrencies but from the information I got, it has failed. The descriptions I got really told that this Exchange served very much okay while it was still available. To conclude it all, 6x .com is a dead exchange.
