For getting some coins faucet is a possibility (you can try freebitco.in: around 600 claims/h for 30 000k sat) but you can't get rich with this, you will also get only a really really small amount (around 50sat) so it is better and more profitable to collect recyclable rubbish and sell that...
. Starting Trading with no know how and not enough money is really risky... you will loss more than you gain.
The easiest way to start into crypto is to buy some and hold theme till you think it's enough profit, But Attention don't invest in Shitcoins. Use stable coins like Bitcoin, Ethereum, Litecoin or Waves...
1Sat is 0.00000001 BTC
