x) Monetize the web. Put your address at the bottom or your blog posts or youtube videos, and people can pay you a bit if they like your work, without having to go through third parties or paying high percentage fees.
I used Operation Fabulous for advertising. No frill, no fuss. Not the most sophisticated and useful advertising platform on the planet but it's very simple.
Its inspiration, "Project Wonderful" uses paypal but I sweat over the chargeback possibility of paypal. Plus it take them a day to pay me. (Not to mention that you have to be 18 in order to use. I am 20 now so it doesn't apply anymore...)
That what I like about bitcoin: bureaucracy eliminated.
You can build your business outside the regulated market to avoid the hassle. My magazine doesn't care if you're a dog or a 3 years old, you're going to get paid for work you did and upon what we agreed on.
Plus teenagers can engage in commerce as they wishes and how they like. I wish bitcoin is available when I was younger.
My only wishes is that it shouldn't be so much of a hassle to use public cryptography to sign constantly changing employment agreement. (I just switch over to ransom payout instead of a constant paycheck but I have yet to update an employment contract) However, that's not Bitcoin's fault, but the lack of infrastructure for the emerging Bitcoin job market.
