I also first got to know crypto through faucet sites. At that time there were no mobile crypto wallet apps, so I only joined hot wallets like Coinbase and Blockchain wallet to store Bitcoin that I got for free from faucet sites. At that time I also didn't think about how to convert BTC to fiat money because BTC was starting to be used as a means of payment. Currently there are many crypto exchanges where we can exchange crypto for local money, apart from that we can also exchange on P2P exchanges. I also don't understand much about crypto but I have to learn about the crypto world.
