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?
No. I'd rather have a stable paying job first before venturing to bitcoins because you need to wad in cash to make a more prosperous reap on bitcoins. You have to buy at the most optimum price point before you invest more. That's more profitable than actually buying at a high price once bitcoins return to its original or rising price.
