I can't give coins to my friend

Hi, because I can not give more than 10 coins to my friend, also says that I must wait 72 hours and I do not understand why it is too much

because the Coins you gain via Trade/Gift are locked for 72 hours.
During those 72 hours you can use them only on "Store" and "Service"

After 72 hours they become usable everywhere (like normal "donated coins")
