It took a great deal of effort and time before I could come up with something tangible about this exchange. The exchange has multiple information online which made it hard for me to come up with a straightforward review. On Revain, the link of this exchange provided is qbtc dot com, I tried it out but it wasn't accessible.
On CoinMarketCap, the link of this exchange provided was qbtc dot ink, I also tried it out but there was no access to the website.
On CryptoWisser, the exchange made it clear that, the exchange changed its URL from qbtc dot ink to qbtc dot me. Even after trying out the new link, it was still not accessible.
I also checked the Twitter bio, but it was qbtc dot me that was there as well, but since it was not accessible, I concluded that the Exchange had closed down.
