Thanks OP for answer my questions, and I just stumbled upon one more.
In the post it states
For every 777 sentences you chat, we will pay 0.003BTC.
When it says
you chat, does it mean if anybody posts 777 sentences they win? Or does the person who posts the 777th post of every person there win?
For example, User 1 made one sentence, and User B made another sentence. It will be 2 sentences in total. Till User C made the 777th sentence, then User C is the prize winner. Afterwards, the number will return to zero, and the rest is the same.
