That site only has a fraction of listed business accepting bitcoin. With places like bitpay and coinbase making it simple to integrate into websites and use for payment that site only has a fraction of business and growing every month for more business to accept payments. I would think that the BTC market is far from it turning dead. BTC at the moment is on a down trend due to many factors that happened last year and still trying to recover from it. Once this has recovered and less down trend and less spikes up and gradual increase in price it will eventually recover but still it has a fair bit of work to get anywhere near what it use to be. Just enjoy the low price of coins for the next few month and grab what you can for the take off and up trend of it.
