Send coins on my alt acc

is there ANY way to send coins that i've earned via trade section on my alt acc, i really have nothing to buy on my main acc, and i wanna buy some trinkets on my alt acc. But atm it says i have 0 coins to gift ??? but i have plenty of coins on my acc :/

No, there isn't. Gifted and traded coins are only useable on the account receiving them, they can't be forwarded to any other account.
