Meanwhile, bullishness around bitcoin has stoked appetite for other cryptocurrencies.One in particular known as ether is getting traction.This represents a 2,367 percent rise year-to-date.Ether runs on an underlying technology called Ethereum, which is a different blockchain to the one that underpins bitcoin.While ether does have digital "coins" like bitcoin, companies are more focused on how the Ethereum blockchain could be used in real-world applications.Ethereum has been designed to support so-called smart contract applications.A smart contract is a computer program that can automatically execute the terms of a contract when certain conditions are met, potentially taking a lot of the human involvement out of completing a deal.Barclays for example, have used a form of this technology to trade derivatives.How is it different to bitcoin?Firstly, Ethereum is a lot younger having only been started in 2014, whereas bitcoin began in 2009.Ethereum is also focused on smart contracts, while bitcoin is very much about payment technology.

Why has ether rallied so much?While bitcoin has been getting support from certain governments and investors, the Ethereum blockchain has been backed by corporates wishing to use the technology for smart contract applications.A group called the Enterprise Ethereum Alliance (EEA) was recently founded to connect large companies to technology vendors in order to work on projects using the blockchain.Companies involved in the launch include JPMorgan, Microsoft and Intel.On Tuesday, the EEA announced another 86 firms joined the alliance, which is adding growing legitimacy to the cryptocurrency.At the same time, the rally in bitcoin has seen investors turn to alternative digital currencies as well as attracting a broader investment base.A year ago, over 83 percent of ether buying happened with bitcoin, according to data from CryptoCompare, showing that it was mainly crytocurrency enthusiasts interested in it.As of Wednesday, bitcoin accounted for just over 32 percent of trade while fiat currencies such as the U.S.

"I don't usually trade ether.I'm afraid of that bubble bursting, but it could go on bubbling up for a long time still."Barry Silbert, whose Bitcoin Investment Trust made it easier for mainstream investors to bet on bitcoin’s value, is looking to create a second trust later this month focused on a different digital currency: classic ether.ethereum gatewayThe new trust will buy up and hold classic ether, which can be a hassle to obtain independently.litecoin low sharesThe new financial vehicle will be structured exactly like the Bitcoin Investment Trust, run privately and available to accredited investors, such as those those with a net worth of more than $1 million or with $200,000 in annual income.It will also have minimum investment requirements, which are yet to be disclosed.Eventually, just like Bitcoin Investment Trust, it may start trading over the counter, Silbert said in an interview.

The bitcoin trust, started in 2013, is currently waiting for approval to list on the NYSE Arca market.By increasing demand for classic ether, the trust could boost the price of the digital currency, which is less than a year old..Prices for bitcoin and other digital currencies have been surging, partly on a bet that their value will be increased by attempts to make them more widely available for trading.It was created after infighting among holders of ether, a separate currency that now has a market value of about $1.48 billion.Classic ether’s development and rules governing the nets; recently, developers announced there will be no more than 230 million classic ether tokens issued -- a decision that makes the digital currency a scarce resource, just like bitcoin.Sponsored by Grayscale Investments, which Silbert founded, the Bitcoin Investment Trust emerged when bitcoin cost around $100, a far cry from its current price.The trust now has about $220 million in assets under management.“I think we’ve demonstrated success,” Silbert said.
