You can earn by doing something you are good at as a service for others and take BTC in exchange, if you don't wanna work for bitcoin you can claim trusted faucet sites and join signature campaigns and other tasks which pop up in service section on here.
I would not recommend faucet for the reason that it may be trusted but frankly they are just not worth the time for the returns. Instead signature campaign is a yes and also Trading is a good option if you know the art and you can actually make money in both upswing and also during dip in the market .
Yes you are right.
Now when Bitcoin has crossed $4000 ($5000 in India), using faucets to earn Bitcoin is nothing less than a joke. At max you could make 100-200 satoshis per day with one faucet and working with 50-100 faucets a day you could barely make 200-300 rupees spending 3-4 hours which isn't recommended at all.
There are still many fancy options which could yield you much more money than faucets.
Signature campaigns are viable option but it isn't game of every person. You need to build knowledge as well as writing style to earn good.
