The price of bitcoin is up nearly $100 on the day, rising more than 5% to reach a high of $1,814 on the CoinDesk Bitcoin Price Index (BPI).

In particular, protocols like Ripple Consensus Ledger, developed by San Francisco startup Ripple for cross-border transactions, and ethereum, a blockchain for smart contracts, have begun to develop unique value propositions that appear to be winning investment dollars.

Ripple's XRP token, for instance, is up nearly 6,000% on the year, while ethereum's ether token was up nearly 1,000%.

The development has not gone unnoticed by exchange and brokerage operators.

In response to questions about how new customers are behaving, Bram Ceelen, co-founder of cryptocurrency brokerage Anycoin Direct, reported they are "pretty much buying everything", a statement that's consistent with the current speculative appetite.

Andrea Medri, founder of cryptocurrency exchange The Rock Trading, however, voiced his optimism that bitcoin would continue to establish its own value proposition, even in such an environment.

"[Bitcoin] always retraces itself," said, adding:
