Are you referring to the high hashrate? that isn't a requirement for the "2 transactions per second". It is basically unrelated. It would work if everyone turned off their computers and the hashrate dropped to one except then I would turn on my computers and earn all the bitcoin instead, which nobody else wants to happen when they can be earning more bitcoin than I I think it is pretty clever and the network works very well. Your criticism is about its future scalability? Transferring bitcoin right now, has worked just as well as it worked back in 2012. You send it from one address, to another address, and it gets there in the same time period. You could ignore all the drama for the last four years and your transaction would still work. Just as much as you ignore all the board meetings that VISA has, that SWIFT has, that the engineers at FEDwire have. The scaling issue is a fun thought experiment, but it really doesn't matter for you actually using bitcoin. Which promise are you criticising? How bitcoin is supposed to compete against the US dollar? I've got the cast and crew of the Panama Papers over in cryptocurrency now, and it works really well, while people are still questioning what bitcoin even does. 2012 is over, shit still works.
