all things can happen, especially if you are optimistic and keep trying, but if you only have one account, in my opinion it will be a little difficult to get faster profits, if you have more accounts, then you can follow several bounty campaigns and be faster in generate profits and can get 1 bitcoin in 1 year.
Yes, it is possible to get one bitcoin in a year. There are several bounties that you can join. You may be able to join one signature bounty only but when it comes to social media campaigns, you can join them simultaneously and you can also apply for other campaigns like making articles, or even as translator because it pays higher for most bounties. You can study another skill like making signatures and then find someone who needs your services. You can do it as long as you keep working hard.
