Where should I go in the virtual currency world?
there are a lot of places for learning. learn from anywhere you can. start with learning. then think about earning.
I don’t have the funds to invest.
90% people here including me don't have any funds to invest. so don't worry about that. if you don't have now you'll have in future. or you will find another ways to get bitcoins.
I don’t have a premium account for bounty and signature tasks, but the cruel reality does not have much time for me to learn.
you don'tneed a premium account to join bounties. you need skills and talent. join social media bounties. article and video bounties. all other bounties you can join don't need a high rank account.
