I don't know how a 210x can already be considered to have factored-in that a lot of transactions will be conducted anonymously / privately
I do.
It's because 5 years of technical evolution, promotion, being battered to death in the media spotlight and surviving, having ETF's being applied for and slowly making their 2 year journey through the regulators and being seen to have "the end in sight", has umpteen GH/s of hashing power on it and a huge worldwide infrastructure supporting merchants.....(on and on)... trumps a 4 month old piece of code that's reproducible and made by a couple of guys in their spare time by about 200%.
