This exchange are been recognized as a recognized trading platform by the coinmarket Cap. Which makes it a good Exchange for trading. However, this exchange exist in different versions. The Lupbit Indonesia is the Indonesian version of this exchange. As it is mostly written and programmed mainly to the Indonesian traders. Non Indonesian traders will find it very hard to trade here. This is because the information and instructions are all written in Indonesia. Although,this exchange has quite a good trading volume.
I couldn't trade on this exchange also, since much information are not provided about this exchange, and the language support are very limited.
upbit Indonesia is still a functioning exchange, but mostly dominated by the Indonesian traders. Also available in Mobile apps. If you don't understand or speak Indonesia, there's no way you can trade here.
