Trading is not sure that you can make a good profit in trading.. it always depends of the altcoin or bitcoin  price movement..
You can not still say that trading is your full time job even if you have a large amount of capital to trade it..
It can be possible that you can be lose in trading.. if you really want to be a full time in bitcoin just apply in any well known company here and offer your skills to them not stay at one company you should do multiple company so that you can make a good amount and you will not wasting your time while you are in front of your computer.

Yeah if you have high capital then you can expect good profits even from small fluctuations, and if your investment is lower then even profits will be lower.

Though trading can earn you huge profits if you have a good enough capital but still you cannot just rely on that because we all know that sometimes we also pick up loses in trading so if you don't have a real job you may face problems if something like that happens, so trading should always be the second option for you if you have a real job.

Wow, that is a lot of opportunity you are having their, I like your method because you are not only focus on one venture. That will minimize the risk because if one will be gone you still have another source of income, you continue that and give emphasis on business that gives you more benefits.

Its kind of wizzard to be able to live with 100 dollars montly, for me it would require atleast 1-3 btc monthly as income, but i wouldnt left my real job as i can get my salarie and a good extra with bitcoin, soo i can retire sooner.

yeah i think earning $ 100 per month would be less? especially if you live in a country that has a high cost of living? I think the least you must have a monthly income of 1-3 before you try to work full time in bitcoin. for now I have not reached it

Yeah minimum 1 btc is required to live a good life and if you cannot manage to earn that amount regularly then its better not to quit your job or else you will find yourself in trouble.

Yeah you may find it difficult to earn that amount initially but over a period of time when you have different methods of earning you can get to that amount.

Yes and if your earning from bitcoin exceeds your salary then you can think of quitting your job and get full time into bitcoins but make sure that you earn that amount on regular basis.
