I am disappointed to be having decentralized exchanges as a scam exchange this days. Years back, people prefer using decentralized exchanges than the centralized ones as the decentralized one is more reliable and trustworthy. You will rarely hear any case of breach of security about decentralized exchanges. But now most exchanges will use maintenance as their own form of excuse. BarterDex is q decentralized exchange that claims to be on an upgrade for over long period of time now. I wonder the type of maintenance the exchange went off, they gave only keep their users hopeless. Though during it existence, I was able to trade many types of cryptocurrencies easier and faster with an affordable trading fee. Meaning it is highly liquid. But today this features or services rather can't be enjoyed again as the website is not even connecting. Please be aware of scam.
