Start with faucet if you don't have any bitcoins to use for other investment and after you accumulate enough balance then try to learn trading's since for this you can earn decently but you need to have a full understanding so that you will not lost your money.
He'll probably get bored before he can accumulate a good amount of sat to start trading. Faucet nowadays are pretty much useless and can waste a lot of your time instead of doing it for something useful in the long run. I would rather upskill, do some freelance works and get payed by bitcoin. Take note that earning bitcoin is pretty much the same as earning with fiat. You'll have to do your job, exchange your time for money and get payed.
@OP, identify your skills that you can offer to other people, get payed by fiat and convert them into bitcoin or perhaps find some crypto freelancing site to get direct bitcoin payments.
