Tradeogre is an exchange that left many information hidden from the public as their website doesn't inform the public about whether it is licensed or regulated. It doesn't give information about the team behind the exchange or the base country.
However tradeogre has been in existence since 2018 and it is still operational. The exchange boasts of a few crypto with many altcoins. Crypto on the exchange include bitcoins and litecoin. Tradeogre is also a crypto only exchange hence no flat currency supported.
The deposit fee charged on this exchange is quite within the industry standard. It charges only 0.20% on both takers and makers. The withdrawal fee varies from crypto to crypto.
However besides the fact that the exchange is not transparent, the security architecture is not known. Hence users discretion is necessary.
