Is it worth spending time to collect Bitcoin rather than having a daily job? What I mean is that can bitcoin be more economical? Has it ever happened that people lose their investment value rather than benefit from spending it on bitcoin?
Use the real life job in order to purchase bitcoin. You wont really earn a serious amount of value with the traditional passive methods of earning bitcoin for free (faucets and this forum, basically). Consider getting a job that pays in bitcoin, this is like mining with your time. with that being said, it is very easy to work online, and you need to be decently skilled in whatever you choose in order to make a wage that is more efficient than again, getting up and working out of the house
also, there are disadvantage to have a bitcoin salary. even of you are pegged to a fiat rate, a bad week (hell a day) and your paycheck will be worth much, much less than you calculated for you budget.
