Well, in 2012 if u invested $100 in bitcoin, it would have become $300 by now. 3 fold increase in investment within 3 years is good 
Hehe yeah not bad, but too bad I spent it on something else
Hi welcome to the forum, like the rest of us i bet you wish you bought straight away, you'd be rich!
I have a friend who bought some when they where $2 lol! He used it to pay for something back then too... he still buys today though at current prices.
And yeah I wish I had learned about Bitcoin sooner... oh well, it's the future of finance, looking forward to the day that it truly encompasses the entire globe, like the internet of today
