Well this is very much on topic. I would like to know if anyone can answer how Monero replaced LTC at Poloniex as the second trading coin?
I could speculate (like the title of this thread asks me to do), but someone must have an answer
You mean why there is a market with XMR pairs? The Tab?
I guess it could be because monero volumes once likely saved the exchange after a hack occured years ago. Or busoni saw a future + a good possibility to atleast trade the cryptonote coins with each other with XMR base pair.
