Buttercoin, a bitcoin exchange startup backed by Y Combinator and Google Ventures, is closing its doors this monthafter failing to raise new investment.

Buttercoin will be turning off our service on April 10th at 11PM Pacific, the company said in a note onits website. Be sure to move your bitcoins to another service and remove your dollar balances by Friday April 10th at 11PM.

Any unclaimed funds will be returned to the accounts that they came from, the company added.

Unlike other bitcoin shutdowns, which are often triggered by hacks and result in customers losing money, Buttercoin is solvent and will provide users with their balance in full. The startup said it is winding down because it wasnt able to raise new funding thats something it attributes to a dip in bitcoin interest among Silicon Valley investors.

Buttercoin launched in 2013with the aim of tackling the global remittance space, aka money that migrant workers send to their relatives backhome. Its a huge opportunity The World Bank estimates that some $515 billion will be sent in developing countries this year and Buttercoins take was ambitious, it wanted to open local exchanges in a range of countries to facilitate cheaper cross-border currency transfer.

Buttercoin raised a total of $1.6 million from investors, includingGoogle Ventures Kevin Rose and Chris Hutchins, Reddit founder Alexis Ohanian, Floodgate, Initialized Capital, Rothenberg Ventures andSwitzerlands Centralway,via its first early-stage investment fund.

The rise ofCoinbase, Bitpay and a handful of others which have sucked upmillions from investors and won big clients makes the chances of a smaller player breaking through less likely. Even when that player is backed by reputed people and institutions.

Might this be the first of many casualties from the consolidation of bitcoin? We shall find out.
