People use other cryptocurrencies like ETH, LTC, BCH(like it or not), etc too. But compared to BTC and ETH, sites/services that use some of those other coins are definitely significantly lower. Also, take note that some(or most) of the coins are still in their very early development stages, so expect the usability and adoption to be very very low.

Indeed we have seen many projects recently which are giving out their tokens as utility purpose and thus they can make good deal with the purpose that you are finding here. It is your misconception that only BTC, XMR coins are being used as payment methods or as currency purpose. There are almost every coin which can be used as utility token in their own site and also now a days with shape shifting and many mixing sites you can use any preferred altcoins as they can convert it to the required coin at the end user. Thus making it simpler and better than just BTC/XMR. I believe ETH is also widely used and more than enough in the ICO payments.
