It was through collecting my "hard earned" satoshis through the faucet I installed on my cheap Android phone back in the day (it was named something like hotBTC or something? the faucet's logo was a flame); withdrawing those few satoshis to my freshly installed and backed-up Mycelium wallet.
Man, those were the days.
Lol.... Cool experience guys, I still remember how the first time I used hotBTC and freebitco. Collecting satoshi little by little in the hope of getting rich off the street collecting bitcoins from the faucet site. Maybe if I didn't know this forum, I could still be there and take a little bit of sathosi every hour.

Besides using faucets to get satoshi, I'm also looking for cloud mining sites that provide free hashrate. At that time I found quite a lot of sites that provide free hashrate.
The good news, none of the activities above can make me withdraw bitcoins to my wallet. It was a waste of time, but it was a great experience and made me know bitcoin even more
