...I would go back in time to enjoy the passion of fellow bitcoiners, busy talking about the currency of the future, having fun finding blocks with their CPUs and GPUs and getting excited to buy stuff with bitcoins.
I don't care about exchange rate, I find this topic pretty boring. But I find it frustrating not being able to buy a bitcoin (because it's too expensive and too volatile), not being able to use my computer to mine some blocks and not being able to join interesting discussions about the future of this fantastic invention.
Nowadays if you want to mine, you have to build an ASIC farm. If you want to buy some bitcoins, you have to choose the right time because the exchange rate goes from $900 to $600 in a second. If you want to buy something using bitcoins, you have to check the price twice because it keeps on changing according to the exchange rate.
This is pretty disturbing and frustrating. Bitcoin wanted to change the money world but everything is getting back to its basics...profit, profit, profit.
