Are you inspired by those bitcoin millionaires? Are you thinking of filing a resignation letter on your day job (if you have any) and focus on bitcoin instead?
Me? I do have a day job and I consider bitcoin as my side job. I don't want to lose that another source of income just because bitcoin is awesome.
I would love, but to do so I would need a monthly income that allows you to pay all my expenses.
sharing bitcoin all over the world would be a very interesting work
I say its very rare for someone to go full time, because like you mentioned "expenses" can add up and the value of btc is far too low still to cover it.
The person would have to produce or have more btc to make up for the low value, overall.
But in getting 100% with btc, a person have no limits on earning.
and also in case of some signature campaigns there is no limit on earning bitcoin and we have to decide that how much we want to earn weekly/biweekly/monthly
Leaving your job to spend full time on signature campaigns is nonsense. You will never make enough money for it to be worth it and it's a dead end, once you reach Hero or sometimes Sr Member because most of the campaign runners are paying the same for Sr than for Hero and Legendary, you can't really make any more money. If you post something ridiculous like 100 post a day or something is just not worth the time, any regular job pays better. If one could outsource this somehow and make passive income and keep growing it would be worth it, but it depends on you being basically all day churning out posts which is impossible long term.
I think he is referring to creating much accounts and then doing signature campaign from all those.
But in my opinion it will be very very easy in first but as time passes by you will regret your decision of quitting your day job.
Even if he did that, it's way too much work, at current rates you would need about 2500 post a month to resemble anything that compares to a minimum wage in the european countries (and im talking about the south european countries, forget about making as much as germans etc).
The time spent would be insane. Literally from morning to night with no breaks from weekends. I don't think that's viable long term. Also again, you would need to tax your money, because how are you going to pay your bills then?
And if you want to buy a house or a car, you can't unless the money is taxed. You can only buy other less expensive stuff and hope you never get audited.
