Not sure if you don't understand the meaning because of language barriers or because you don't like the concept but just in case because "TIP" does have many meanings in English.

I didn't talk about Language barrier. Yes I meant Do we need a sending money button shaped "GIFT BOX"?. But you already answered this. Thanks

I can't understand can people send tips from out side of Hive?
If you clarify the question I can help... are you asking how it's done or why?

I meant, If I don't have a Hive account, Can I tip the post with Bitcoin, Dogecoin etc.?

As I told I think that button is not needed if you can't send TIP without a Hive account with other currencies.
