Bitcoin has really lost a lot of its value over the last few months. It seems those who sold all of their BTC did better.
Nothing would annoy me more than having the rules changed in the middle of the game. However, a game like this one should from time to time, introduce a haircut fee and other things that we see in the real world. A fee for inactivity or simple confiscation does happen in bank accounts but this does not happen in bitcoin accounts. Randomly, users should lose all of their holdings bitcoins out of those who have traded recently in order simulate hacking of exchanges for you really can't instantly remove your bitcions from the exchange, and those who are not trading will have their bitcoins in keys they control .
Holding for now.
sdp
the losses are not random.
In the Gox event there have been reports of withdraws delays and other signs that the exchange was about to collapse before all the withdraws have been disabled.
It is not like an exchange is working fine with no complains from anyone and all of sudden they disappeared with people's funds
(by the way, I'm active, please don't Gox some of my funds)
