Since bitcoin is trending now world wide because you can easily earn this and it exchange in real cash. [...]
You don't seem to understand what Bitcoin is. Bitcoin itself is real cash. It's clearly a much better form of money than fiat, because - among other aspects - it is not subjugated to interventionist monetary policy that inevitably leads to full devaluation. Bitcoin is a currency in its own right, it does not need to borrow legitimacy from fiat debt money.
New era of currency maybe not, but Blockchain perhaps yes.
Well you guys have to understand that even as times move on, bitcoin will also evolve. Im looking forward to new use cases. The bitcoin team are always testing out new protocols.
What utter nonsense! You seem to be falling for the blockchain hype, started by cognitive dissonant bankers that desperately try to thwart the fact that Bitcoin is a monetary revolution that will sweep away the fiat scam system, which is the justification of their existence. The real killer app of the blockchain is sound, decentralized cash (= Bitcoin), all other use cases are merely optional additions. In fact the blockchain is a highly inefficient way for most proposed use cases.
ya.ya.yo!
