you will notice that a fairly significant amount of ltc is being used on polo to buy Monero directly and at a significant premium. It appears that people are buying ltc to avoid the fees of btc, sending it to Polo to purchase Monero.

We really need to make this easier for people to spend fiat for Monero!
