More options indeed possible but I think that trading is a good one and maybe some sig campaigns are also a smart thing to do.
Trading and signature campaigns should not be considered a stable income, trading is similar to gambling and a signature campaign can end at any time as stated above. Although the campaign i am in has been stable for a long time now so it does not apply to all of them.
I think so, bitcoin is related with computer, so if we want to make steady income in bitcoin, we have to learn computer skill to make an exchanger or the similiar thing. Also we can build online shop that rrcieve bitcoin as payment system.
Making an exchanger is not as easy as you think. It needs dedication, time and money before you can start your own.
And remember that you can just do it alone, you need to have also a dedicated team where you can trust everything with them.
It is just the same with building your own online shop.
