Binance has just temporarily suspended Luna trading to protect the traders from a free falling coin, but once people became aware of what's going on, they eventually resumed it. Though some other exchanges are delisting it, some few others are resuming as well. There were still people who are actually buying it. I myself even thought Luna would die down immediately, but no I guess they're trying to revive the project back. A lot of people are actually FOMOing right now lol
