My first time hearing about bitcoins is from my technician friend.He told me everything about it and how its value rise up to $600 from a starting value of $0.01 per bitcoin back in 2009 or 2010. I hope i listen to him earlier and stake many btc as i much, if that happened i am very reach now because a lot of money that time because i got my shares when our land property is sold for 500k$. My bad. 
i heard about bitcoins from my friend too though at first i did not invest and thats why i actually missed a chance to make moneyYeah even my friend was forcing me to invest money in bitcoins when price was not too high, but I didn't show any interest at that time and regretting till date for making such an worst decision.
