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?
If the user is only earning at his/her free time, it would be worth it. Gaining money while relaxing, because it is either determined or not. Those who are determined should maximize their time by earning at all possible bitcoin site, because holding onto one site will not be enough since the user invested time and internet connectivity, also electricity in doing it. But in the long run a user can earn a lot by being patient and wait to earn and start getting interest that can be daily depending on the site.
