I am so impressed by how XLM (Stellar) works - it is very similar to XRP (Ripple) but these guys have a mission. The protocol is fast and rather cheap.
I use it if I want to move coins between exchanges, works great, here is my article about it: https://ecency.com/hive-167922/@ghua/transferring-crypto-around-the-cheap-way

I have been using LTC at times for the same reason :)

I used to do it as well few years ago, now it is too expensive :P
