Hello and welcome! I suggest you read the newbie readme and also this Bitcoin guide if you want to learn more about BTC.
Thanks bro, ¿u are the founder of primedice.com?
No, but they pay people for having their link in their signature. Once you have 50 activity (takes 1 post/day for 50 days) you can also do it, if you want. The link to the official thread explaining it can be found here: https://bitcointalksearch.org/topic/primedice-staff-only-earn-bitcoins-simply-by-posting-291387
There are also some other sites doing the same thing, but I cannot guarantee if they will actually pay you. I can, however, confirm that PrimeDice will pay you (or they have in the past at least
).
