There are Bitcoin faucets. They give you a tiny amount of BTC each time you play a game or click on ads. This one is legit https://freebitco.in/?r=4129230 so give it a try.

But faucets require you to be very very patient. If you spend a lot of time on the Internet, you can play freebitco.in every hour and gradually build up enough to transfer into a trading account or even Coinbase.

But like I said above, you can buy cryptos with pocket change, even $5 or $10 is enough to get you started.

I forgot to mention localbitcoins.com. It's like craigslist for bitcoiners. You look for sellers in your area, give them fiat currency and they sell you Bitcoin. All you need is a Bitcoin wallet app on your phone or computer -- and those are free!
