I think it is a good investment in the probability of recovering in the price, I don't know about how safe it is since BTC price moves rapidly and with huge volatility so 1 BTC might worth less than half of it's value now after sometime.
It couldnt be safer than gold obviously but atleast it is much better than a barrel of oil. The volatility is an indication that there are alot of movements in bitcoins than that means there are alot of people that are taking an interest in bitcoin so it this continue then bitcoin would be comparable to gold someday
