What coin do you use between exchanges?

BTC and ETH are the blue chips but their associated transaction fees are not to be sniffed at. Hence, in order to preserve my wallet, I routinely convert these assets to Litecoin when I need to transfer them between exchanges.

LTC has several advantages: low fees, zero downtime, wide availability. But I know that these advantages are not exclusive to it. There are similar coins with such characteristics, Nano and XLM being two of them.

Do you have a coin that you stick to when it comes to transferring your crypto between exchanges? Or do you vary your use of these coins depending on the situation?
