So, what's new in these suggestions ?
Nothing!
We all know this.
"Learn a skill what is in demand"-> I mean come on!!
Not everybody for instance can learn to write code and will be good in that for instance.
This thread is useless.
Just do what you can do best and exchange some of that earnings into Bitcoin if you can afford it.That's it!
In bitcoin world, the most needed skills are about software, nodes, graphics design, write code, web design, hardware, operating system, which not an easy way to learn.
Work and earning fiat money than buy bitcoin may the good way as the price could rise in the process.
But why Op stated that earning through sig-camp is the worst way? It just another way in case to make bitcoin through advertising jobs.
Everyone is free to do any kind of effort to earn bitcoin as long not harm anyone else in my opinion.
