The '1 trillion market cap' thing isn't quite true because of the fact that a large proportion of the coins mined early on have been lost, creating artificial scarcity. However, perhaps the best boost that will come out of this is if Bitcoin approaches the market cap of silver, in which case it'll be difficult to treat Bitcoin based on its original purpose (as a P2P electronic cash system) rather than a digital asset which seems to be how it's most often treated now by speculators.
Now that Bitcoin has cemented its status as a trillion-dollar asset among the likes of Amazon, Apple and Google, legacy banks are showing increasing interest in offering cryptocurrency custody services for their customers.
Amusing. Doesn't that defeat the whole point of Bitcoin, to have a digital currency without the need for banks as an intermediary?
