One of the biggest roles that stablecoins can fill is the ability commerce side of things which is what I am focusing on over at @hivelist. It’s much easier to deal with stablecoins for things like that than volatile currencies like BTC. Yeah trading is a good use case. I am trading allot on the Hive internal exchange lately. I out all my profits into HBD savings then pull it toward the end of the month to pay bills. Anything extra goes to LTC.
