So..... I managed to earn 0.1
BTC 
with the 0.1
BTC what is the fastest way to get more BTC?
I can only suggest you to trading because only trading have a low-risk level than other, and your age from now is 13 years old. I can't suggest another way to you because it's will have a riskier if you fail and you will lose your fund..... or you can to try faucet but it needs to take a long time....
