Multiple Choice Question:
Do you see bitcoin in the future as:
A) a scaling peer to peer network with ultra cheap transactions, for anyone globally to use, with bitcoin functioning as internet cash, avoiding financial intermediaries or banks.
B) a settlement layer for banks, fin tech companies and early adopters, with a low volume expensive to transact upon blockchain
C) all of the above, and more
It's a trick question (false dilemma fallacy), because of the duality of big-B Bitcoin (the first successful e-cash implementation) and small-b bitcoin (blockchain technology).
Small-b bitcoin has already forked, in the form of alts, so as to ensure ultra cheap p2p global tx for all mankind.
Big-B Bitcoin, still in its early life cycle, is in the phase where it distinguishs itself and diverges from Bitcoin-like blockchains, on the way to becoming the (ultra-secure, expensive, low volume) Mother of All settlement layers and global reserve e-cash.
The commonplace category error plaguing us at the moment results from failing to recognize this bifurcation (and reading Satoshi's Whitepaper in that context), or refusing to countenance the existence of alts (IE small-b bitcoin) because of some nutty Maximalist Monopolist Fundamentalist Supremacist ideological stance.
