About BitcoinVN
Built specifically for Vietnamese Traders, BitcoinVN is the digital platform that deals with buying, selling and trading of Bitcoin and other altcoins with Vietnamese Dong (VND). The exchange only supports Vietnamese Dong as its only fiat currency which means that this exchange might not be convenient for foreign traders. Personally, I don't like the interface of the exchange because of its unattractive nature. The exchange on the other hand, provides updated prices of all the cryptocurrencies traded. My main reason for not trading here was due to the unknown status of rhe exchange like the trading volume, the trading fees and negative reports about the exchange from its users on Telegram who claimed to have purchased Bitcoin and Dogecoin but it never reflected in their balance but there hasn't been response from the admin.
