if bitcoin would go considerably lower than now after a 9 months decline and the paypal news i'd consider it failed and move to the next coin with lower inflation, really.
Freakin' inflation killed it.
Buy some Uno, they got the inflation-part right. It can replace bitcoin any day. Not a problem. Cut the freakin' inflation.
Lower than 300$ --> dump it, never look back. Wait for the halvings. Till 2016 it'll be back to 50$ or 10$ then. Hold some Uno to save your day.
And the alternative is.... Unobtainium?
well, if it would have been uno in the situation of bitcoin with same amount of total coins but different rewarddecrease we would probably be now in a bullmarket since mid-summer and at 2000$ a coin. Just sayin'. Bitcoins inflation sucks ass right now.
