Once that's accomplished, MC and Visa have essentially written their own epitaph, as there's a dozen companies developing direct p2p transaction platforms to instantly swap currency.
But the most exciting part of blockchain isn't its ability to add and subtract balances. It's in its ability to provide transparency, or 'trustless' transactions. And in case you think that these ICOs are scams milking people for money, consider the following.
Bitcoin - BIP148 UASF activated, Segwit imminent. Transaction times will be cut into a fraction. Still not fast enough perhaps, but improvements in the flagship are proof that blockchain is coming along.
Ethereum - Has successfully crowdfunded dozens of ICOs
Steem - Reddit for the blockchain. Is becoming widely used in the crypto community
Humaniq - Simple smartphones preinstalled with crypto software for countries that have no access to banking. Instant transactions anywhere in the world.
Patientory - Patient data that can be accessed by (wait for it..) the patient! No more going to 15 different places to get your list of allergies, prescription history, family history, and other records.
Firstblood - Just released a beta where you can play Dota2 betting tokens. I just finished a match (won 100).
LBRY - Just released a beta media hosting service where people can directly access or buy content directly and stream it
Bitshares - Direct p2p exchange with no fees that actually works
Tierion - blockchain auditing tool (Think Crystal Reports for the blockchain) but is still in ICO phase
Civic - Identity verification on the blockchain. Will be used like Facebook login is currently being used on different sites. Partnerships are unfolding.
OmiseGo/EOS/Status/TenX - These will be operating systems that come preinstalled with built in user login, database and permissions so every startup doesn't have to recreate the wheel. These are Windows/Mac OS for the blockchain.
Lots and lots more coming down the pipe. These are just some I'm following. Crypto has a bright future. Banks do not. Fiat does not.
