I haven't personally started earning from PTC sites or faucets, but I can give you my opinion on how someone might have grown their small earnings into a larger sum. I think the key is to be consistent and patient with these types of opportunities.
I mean, when you first start out, earnings might seem minimal, but as you gain more experience and referrals, your income can increase. Reinvesting your earnings smartly is crucial. I suggest diversifying your investments, such as putting some money into passive income opportunities, like staking cryptocurrencies, or even investing in stocks or mutual funds.
