About two years ago when most altcoins were worth at least 40 sats, TradeOgre was the preferred exchange for new cryptocurrencies... Few months later, they paused adding new cryptocurrencies, then they added Ethereum wallet and resumed adding new altcoins... While I was using other exchanges, they added LTC as base currency and LTC pair for a lot of listed altcoins.

When listing by voting became popular, C-PatEx became more interesting than TradeOgre, because TradeOgre hasn't ever revealed their exact listing requirements, they just accept listing applications and stay silent until they list a coin.
