Bitcoins at the moment its just an extra as the income i get from it isnt too much.If i were able to earn for 6 months an fixed ammount of 2btc or 3btc i would be out of my work and full dedicated to bitcoin,as i would be getting 3 times more what i earn currently ,and doing something i like.
i can earn arround 0.2-0.3/week from altcoin trading + bitcoin sign campaign.
but i doubt i will go full time on bitcoin, the main problem for trader is when you pick altcoin and price fail, and you need money to life, then you sell your altcoin at under valued.
i think we ust have more capital to live, maybe we must start sving some amount today for start small bussiness in future.
