You have to have nerves of steel to an extent. I only have about .5 BTC but I was tempted to sell yesterday. Can't imagine what it's like for someone that has their life savings in bitcoin.
I just have a good feeling that it will bounce back up though, the indications are all good, it's really just a fluke that it dropped down this low IMO.
If you put your life savings in bitcoin your asking for trouble, anyone who puts their life savings in only 1 thing is asking for trouble no matter what that thing is.
Bitcoin is a great place to but your un-needed money, but life savings... oi, I hope people arn't doing that yet.
