although there are so many people who are depending on bitcoin for living, but still i like to say that you must have a permanent income from which you can fulfill your necessities, and consider bitcoin as secondary option for making money.
That is what i am doing for now i have an legal work outside and bitcoin is just my hobby since i can't trust my future on this coin aswell as i really make sure that i will not get compromise and have job to really on in times that bitcoins will fail nor i don't get any income from it on weekly basis, and cryptotrading is good source of profit but not an ideal one to really for earning to get a livings,
Its better to have that two so the earnings is double when salary and bitcoins payment time will colide.
