Nice to meet you as well

I can't understand the meaning of "Tipping"
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.

In any case i think most people would not consider voting as tipping in fact that may make some people pretty upset because voters are not giving them money they are simply voting with their stake that some of that days' inflation being put into a rewards pool go to them... and at the end of 7 days based on everyone's votes they calculate an amount. No money is given or even promised to them at the time of the vote and only after ALL votes up and down come in is there a decision made. It really is Just a vote.

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?

Is there account creation limit?
One per phone number as far as i know. You can ask that project more about it but that's what i've been told.
