Most people will either offer a service or purchase it directly as an investment. There's no way of magically acquiring it. It's very much like how you would acquire fiat.
But since the OP is still a newbie, maybe he can join those bounty programs via social media channels, paying tokens or other coins. And once he received it, he can trade with bitcoin. And so he can acquire btc by joining these bounty programs that really do pay. However, if he is not into participating these bounty programs, he can always check the services section and see if his skills are needed. Because sometimes people are looking for individuals with specific skills like in programming and they will pay crypto. Getting coins from faucets is not advisable because you can get very small amount and spending much of your time collecting those free coins.
