There are different way to have your first cryptocurrencies :
You can mine some cryptocurrencies with websites like Honeyminer (https://honeyminer.com/) or Nicehash (https://www.nicehash.com/). Programs like this use some of your computer's computing power to mine with the rest of their community. So more you have power on your PC more you earn crypto. However, you need to check your electric consumption, if you pay more electricity than you earn, it is not worth it. If you live with your parents talk with us before starting mining. Even if you are profitable, you are not going to make $1000 a month but it will give you an additional income. You can see an estimate of your benefits on Nicehash.
The first one is Brave, you earn BAT (Basic Attention Token) when you see advertising. You can earn about $5 a month according to the BAT price. It is very simple and you have nothing to do.
The second is CryptoTab, you can mine by adding this to Chrome or with the navigator CryptoTab to increase mining speed. Be careful it can slow down your PC. With this method, you earn a few thousand satoshis per day (about 50/60 $ a month).
With Adbtc (https://r.adbtc.top/2310156) you will earn Satochis or ₽ when you are watching the ad.
