Learned about Bitcoin first around 2013 on Indian forum called Ethicalhavoc, people were mentioning about Bitcoin in forum's shoutbox, which at that time seemed completely alien thing to me and also illegal.
Then I got Stellar (now $XLM) airdrop, I farmed it with my relations Facebook accounts, got plenty Stellar but sold it all for peanuts, iirc I sold it for about 3.5k INR (~45 USD at current USD/INR rate).
During same time joined bitcointalk (although started being active years after with new account), did faucets, did cloud mining (thinking those are legit, I laugh about it now), wrote articles on sites like Steemit to earn crypto.
Since last several years, been active every single day, it's such a good sector to be in.
Regarding learning, have learned plenty but can't exactly pinpoint what.
