I think blockchains and so-called "smart contracts" should be added to the list of exciting areas to watch. Companies like Paypal are begging to be disrupted, we've all seen the problems of Too Big to Fail banks and the havoc they've unleashed. Globally remittances charge a fortune in fees, just to name another area that seems ripe for disruption by cryptocurrencies. Even big banks are expermenting with private blockchains for asset transfer and verification. Smart contracts are in a phase somewhat similar to the dotcom 1999-2000 boom/bust, some great ideas and some awful missteps like the DAO disaster recently. Even Bitcoin had it's Mt Gox moment, which didn't kill Bitcoin. Eventually the diamonds in the rough will become apparent. Disclosure: ethereum investor/miner
