I don't know about one what I wouldn't enter your login information for one site into another regardless.
Regarding #2 it sounds like you are talking about air drop bounties those are from developers who premined a block with so many coins to spread word through funds or get things done and pay with the funds.
Hello, thank you for answering.
About #1, it is not login information, just info about the user to keep control of the bounties. Where can I find my bitcointalk ID?
About #2, in here for example,
https://bitcointalk.org/index.php?topic=3273444.0 in the article/media campaign they say they reward 10-30 shares per article (this is just an example). What I do not understand is, what are those shares?
Like a fixed quantity of tokens?
