I think If I have the opportunity to earn more in bitcoin industry then of course I will consider quitting my day job. Most of the work in bitcoin industry is done through a computer. I can then stay inside the house and get more in touch with my family. I kind of prefer working at home than going outside to work because I get to see my family the whole day.
it's very possible, but im sure it will consume more eneergy , more your free time must be spend to earning bitcoin
today bitcoin hitprice 738,06 USD, i think the price will be rising more and more, better we keep holding our bitcoin, after we reach our goal we can go full time on bitcoin.
But what if price will drop from $700 to $300 in one day, what you will do? I think that if you are not sure that you can handle this situation you can't work full time on bitcoin.
