I too pretend I know everything, but that is mostly my male ego shining in. I do however learn something new everyday about the latest crypto currency and I am obsessed with coindesk, localbtc and now steemit. With the Euro's uncertainty and bitcoin halving coming up...the volatility alone gives me a rush, but I know that is not the point of BTC. But I was ecstatic when my BTC that I bought for $450, (which was an unbelievable price to me at the time.) sold for $850. I also did not fret when it dropped below $650, I am looking forward to the first and second of July.
