Altcoin Exchanger seems like an exchange focused on conveniently trading mainly altcoins like Ethereum, Tron, and other popular altcoins. As there's no information about the exchange online. It was founded in Czech Republic in 2017 and has been marked by CoinMarketCap as Untracked Listing. Most of the times, the whole page is usually blank which makes it quite impossible to trade in it. The exchange even has its mobile app, but i didn't download it as there hasn't been any review concerning the app. I checked out the exchange on Telegram but i wasn't impressed with what I saw, the owner of the Telegram group has a deleted account and the Twitter account if the exchange was last active as at May 2020. From all this, it is clear that Altcoins Exchanger is no longer offering any trading activity.
