6x .com is one of the cryptocurrency exchanges that is now inactive. I tried to visit their provided website to clarify but I kept on getting these results; "502 bad gateway". However, I was able to get few informations about this exchange. 6x .com is a cryptocurrency Exchange from Singapore, while it was still active, it supported many cryptocurrencies for trade.
I also found out some of these cryptocurrencies; USDX, BTC, ETH, DC, USDT and some others with good liquidity on its markets. No KYC information is required for signing up for an account with 6x . com but how is all this given informations helpful when the exchange is already a dead exchange. In conclusion, I will advise you all to go and check out for other cryptocurrency Exchanges for your transactions.
