> With the dip in bitcoin interest among Silicon Valley investors, we weren't able to generate enough venture capital interest to continue funding Buttercoin.

It doesn't seem too much of a stretch to think that a lot of companies hedged their investors money in Bitcoin and hemorrhaged investment when the bubble burst, leading to colder responses when other companies later went back asking for more. That would seem to fit with stories like this.

They had zero profile in the bitcoin community. Essentially a non-entity. So I can't imagine they had that all-important growth graph investors need to see.

Investment in Bitcoin related companies increased in 2014 to almost $1bn, from around $300m in 2013... not sure what went wrong at Buttercoin but interest in cryptocurrencies in general has never been higher.

Where did you get the 1bn figure from? Coindesk puts it at closer to $400m for 2014.

We're at around $200m for 2015 with 95% of that between 21 and Coinbase.

Just an update actual number is 83% not 95%.
