My basic requirements to do or to have bitcoin / altcoin job is to have laptop or smart phone and of course a good internet connection. In that case you can now create a gmail account and then create an account in this forum. Of course it does end in that, when you have an account it does not mean that you can now work. No. Part of the basic requirements is to read more and more and more about bitcoin for you have knew only little things about bitcoin. Read about what is bitcoin, rules in bitcoin, etc.
After that you can now post to threads but you have to wait a long time to have your rank up so that you can work like in campaigns and you can now earn.
It is not very simple, right? But it is just the same when you wabt to get a real job. You're first at the bottom, have to learn all you have learn in the compamy then you rank up.
You are right that to earn bitcoin or altcoins, one needs to have a laptop or smartphone and a good internet connection but still I wouldnt agree to call bitcoin earning or altcoin earning a job, it isnt really a job to begin with. Why does many people mistake bitcoin as a job, when all we do is speculations and investments to make profit? Also I wouldn't treat joining signature campaigns as job after all one cant always be employed via signature campaigns.
