I became interested when I saw it on the news. There was a report about it on the news where they explained that bitcoin was used for illegal stuff to launder money. That's when I became interested and looked up some information about it on the internet and what the concept of it was.
That's really funny LOL
I mean, if it weren't described as something used for illegal stuff, there's quite a less chance of you getting interest in bitcoins, I assume.
What made me interested in bitcoins is that I saw potential. I've read about the past halving and see that many profited from it. I'm also a stock trader, well, used to. I saw there's trading also in bitcoin (with alts) so it's a plus for me too.
