Hi guys, i'm pretty new to bounties and have seen that there are lots of new altcoin bounties being posted everyday.

I'm curious as to:
1. Do you really earn from joining bounties like this?
2. What is the weekly average amount earned in USD$ for joining bounties if i spend 1-2 hours daily doing it? (not signature campaigns but fb, twitter, telegram bounties)
3. How much have you earned from telegram bounties alone?
