I was first aware of it in 2009. Forgot completely. Became dimly aware again in 2011. Did nothing. Got rolling properly in mid 2013. I feverishly read up on it for a couple of weeks. Looked up Gox, thought 'this is the NASDAQ of Bitcoin? Fuck that' and went to localbitcoins.
Almost all of the 'opportunities' and businesses looked like blatant scams to me and time proved it to be correct. I've learnt vast amounts of new stuff along the way.
Same here after I was introduced to bitcoin by my friend I've been researching it and trying to learn different ways and opportunities to earn bitcoin but it was like walking in the dark specially if you don't know much about the cryptocurrency world. I was overloaded with info and different suggestion of which is safe and better and some of my decisions are turned to failures but I guess it was always part of the learning process and I now have people I can trust and exchange informations with whenever we receives updates and so on.
