Same here. I have never once converted my fiat into crypto. Although bitcointalk.org is not the first place where I got my first bitcoin, but since 2 years ago until now this forum is my biggest passive income medium without investing (financially) that I can use in trading, betting and many others.
I have several times converted my fiat to crypto, but with a very small amount of fiat itself.
But that is not the starter that I did.
I got my payment firstly from joining bounty in this forum and also doing some airdrops at that time. At that time, it really worked enough and this turned me to earn more money from bounty and airdrop.
I also didn't have any bravery to invest my money at first because I didn't have enough money and also still needed to learn much about crypto investment.
But the time as time flows, after some learning, I tried to deposit some amount of money to buy a little bit of tokens and coins and make some investment. However, after taking profits, I withdrew all my fiat and continue earning by not investing again, but by using the payment from bounty nd airdrops
