As a teen (and thus underage), you have several limitations: you won't be accepted to websites like Clickworker and Mturk, and you may also have some issues trying freelance jobs. But that's not a good reason to give up!
First of all, since you don't have a credit card, you should open a Paypal account. You won't be able to verify it, meaning you'll have some restrictions (I believe there's a $2500 deposit limit and a $1000 withdraw limit), but you can still use that to receive money.
Also, if you're planning to earn something with Bitcoins, you may find a Bitcoin wallet useful. You can use Electrum or Copay on desktop, Mycelium for Android and Breadwallet for iOS. No age restrictions here.
That being said, let's get going

- Tasks websites that don't need a credit card address: A lot of websites will pay you to perform various tasks and will pay you on Paypal or through gift cards. Here are some of them:
- BeerMoneyForum: paid to post forum where you earn BMF Coins, exchange them for money. Pretty simple concept. You'll need to write a lot to earn a decent amount of cash, though, but it's fun and not too time-consuming. No age restrictions, and pays by Paypal: all you need is good grammar and a strong will.
- Swagbucks: Your typical survey site. Works best in the US, but it also works in other countries. You can also watch videos or do other tasks. Pays out with GCs.
- PrizeRebel: Same thing as Swagbucks, check this out if there's not much stuff available on it in your country (just use both of them to maximize profit). This one, too, pays out with gift cards.
- Be creative: You claim you have no special skills, but what if you just don't know? Here are a few things you can do (you'll need some offline work, too, here):
- Sell hand-made stuff on Etsy: Etsy is a great marketplace to sell hand-made stuff. You can make things related to videogames, movies or books you like, and then promote them over the Internet. Find your niche!
- Make designs and sell merchandise: Same thing as Etsy, but this time you won't have to deal with manifacturing. Try Redbubble to sell all kinds of merchandise, or Teespring/YeeTee if you're aiming to sell garnments only.
- Make art and sell prints: You'll need good drawing skills for this, so this may not be the right thing for you, but it's great to wake up your inner artists. If you post good art on websites like Tumblr or Deviantart, people may start to request prints of it: don't make them wait! If you can't find any local service that prints stuff, then use on-demand websites like Redbubble or Lulu.
- Earn money with your smartphone: As a teenager, you probably spend a lot of time with your phone, right? Well, I'll let you know there are lots of apps you can use to earn some money, even if you don't have any special skill.
- Perk: This is a passive earning app, you can leave it running while you study/do other stuff. There are a lot of things you can do there, like watch video ads, play with some of their games, or you can even use it on your lockscreen. Only pays through gift cards.
