From what I understand, the opportunity for individuals to profit from mining Bitcoin has passed and it's now the realm of dedicated mining companies and even they are struggling - it requires more and more processing power to mine coins and at some point the power and computing costs become too much.
Of course it can be made profitable from transaction fees which then negates one of the touted benefits of crypto currency plus the miners need to sell the coins which can put downward pressure on prices.
Personally, I think it's one huge bubble and lots of the claimed benefits are either not real benefits at all or will disappear if it ever takes off. Right now it's really a techy / early adopter fantasy and not something that real people use in the real world.
I'm sure the ones looking to profit from it will continue to promote and hype it as much as they can but I can't see it being tremendously useful for regular people without major changes being made which will then change what it is.
Inevitably, the existing payment processing and money transmitting system will be re-invented by new groups wanting to steal market share away from the incumbents.
I read that the BitCoin network only supports something like 7-9 transactions per second compared to 10,000 for VISA (just one of many).
Hype, hype, hype - which isn't to say that peope can't make money from it, just beware ... even the proponents say you should invest money you can't afford to lose.
