I cannot get a good paying job as i am only 15. However I have a good knowledge of many programming lanuages and the running of different things such as bitcoin
Age doesn't matter in the realm of freelance. Act professional, provide quality services, and nobody will even question your age in the first place. If you understand programming you should look into the services section or reddit.com/r/jobs4bitcoins and reach out to people in need of some programming help.
That's true, as long as you're good at providing a service you could work your way up to earning decent amounts of BTC.
Sometimes its pretty stale. I also have my own craigslist sourced bitcoin job board
http://www.honeybadgerofmoney.com/jobs but again, its freelance just the same.
I've done a gig on jobs4bitcoins I think its a luck thing and you mostly have the figures going against you - there's a dime a dozen for the developers there. Something else, like perhaps drawing, or unique talents like maybe some type of astrological charting or maybe a great songwriter seem to have a better wow-factor than the run of the mill developer. Heck, you could give programming and development consultations for micro-amounts like $2-5 with perhaps an outlet to provide and render services @ a discount, but charging your clients maybe $60 an hour. If you really have the skills to back up and could see yourself banging out an app over the weekend then you're capable. If not (like you know some scripts here and there and how to hack together maybe a wordpress but that's it) then you need to go back to the drawing board and study up more.
Maybe also take a step back and look at it from another perspective. If it were instead Fiver and not Bitcoin, and you wanted to make roughly the same amount - like $250 a day. You need to do the equivalent of 50 fiver gigs. Complete. How is this possible? Well the best of the best can do it. Here's how! They will have a HUGE portfolio of past creations, code snippets, project ideas, art resources like photoshop brushes or custom sample work that's been collected over a long period. That makes it incredibly easy to take a couple sentences and provide a quick 7 minutes worth of your expertise this averages down for some where you know exactly what you'll give them and for others where you need a little extra time. @ 7 minutes you will clock in your goal just under 6 hours. Also, work doesnt work that way, its usually waves of work available to be fulfilled and completed in exchange for compensation. The steady paycheck is a myth that business gives to you to keep you in check. Working for yourself either earns you a little bit of money constantly or earns you a lot of money from time to time or it just loses money (your business is having a bad day,week,month,year,is sunk and should be put out of business)
