i know bitcoin before when its price was only 100$ , and i already have a job by then, bitcoin never come out in my mind that it will be so strong and its price climbed upto 1000$.if knew it then that this will be happen i already quit on my job and go full time on bitcoin,.
Well the bitcoin's price is just $100 that time years ago, there are people who are working full time on bitcoin because they know what is the potential that bitcoin can bring.
But for me, it is still better if I won't quit my daily job and just work for bitcoin part time.
I agree, bitcoin seems not to stable at the moment. At least for me. Suppose you get 3 bitcoins per month, today you will have a good salary and the price goes back to 300 dollars, you won't have enough money to live out of it. And you will be in debts before you know.
Which is why i don't recommend it yet.
