I heard about bitcoin first in 2013 from a friends friend who had a few bitcoins. he told that somebody send it to him in 2011 or 2012? for free because he wants to try this thing out. he got it from a forum maybe from a member bitkointalk. At this time I don't really understand what he was talking about. And I thought Internetmoney it couldn't work because you can copy everything an a computer so also Bitcoins. I wish I had an interest at that time to understand Blockchain.
The second time I heard from it was mid 2017 from other friends who have already been invested in it.
