That's a pretty impressive lineup of investors. With that kind of funding, I imagine that Coinbase isn't just setting themselves up as a Bitcoin company, but they should be able to create infrastructure that processes/handles any sort of cryptocurrency. So even if BTC loses favor, they'll be one of the few companies that have the infrastructure to support whatever the up-and-coming cryptocurrency is. Regardless of which specific cryptocurrency is in vogue at the time, I do believe that cryptocurrencies are here to stay, and Coinbase is aiming themselves up to be the market leader. This is an investment that even I'd be willing to buy into as well, if there were ever an opportunity.
