if you really do not have the capital then it will be difficult and you have to work hard to get bitcoin by participating with bounty campaign or playing faucet they will give you a fee with maybe less value or even just $ 30 according to your work. but if you have a capital of at least 1 BTC then you can get $ 30 every day, by the way you buy altcoin with capital 1 BTC you can buy altcoin more than 10 altcoin which have very limited availability and have a very good team or developer, I'm sure you will earn every day at least $ 30 every day.
