During the last event (The one that spawned a ton of Ralts with increased shiny chance) I got multiple shiny Ralts. My friend didn't get any so I wanted to trade him one of mine. But when I tried it said that I didn't have enough stardust. It doesn't say how much more I need it just says I can't trade. How much stardust do I need to trade?
Then later I traded with another friend and we tried to trade again but it said I can only do one special trade per day. Is there another way to trade pokemon so we can do it multiple times in one day?
