volatility makes bitcoin an interesting speculative investment. But without any backing or federal insurance, seems like a poor store of value compared to a bank account (though many currencies no longer have backing...)
> b2b, peer to peer payments
Again, solutions to these (ie. Venmo, Square Cash, Facebook Cash for p2p) do not require blockchain. How does blockchain tech help in these use cases?
