He is right - nobody is using Bitcoin. We have estimates from the FRB, ECB and Jeffrey Robinson which indicates the user base is under 250,000. Schmucks like Coinbase and previously MtGox loved to claim "millions" but addresses =/= unique human users and most of their addresses are empty. Risto Pietila, here on Bitcointalk, has spent countless hours analyzing Bitcoin's adoption.
If this was any other industry or the tech sector then Bitcoin would be considered a fail. A fail in the sense that if it couldn't attain the proof of concept (viral adoption) over 6 years and it probably never well.
In the mean time - Whatsapp is newer than Bitcoin and it has attained 600 million users. Even Telegram app is 2 years old and has 50 million users.
Inb4 "Digital Currency is new" - blockchain might be new but that is about it. We had older stuff like eGold and older predecessors and it goes back to the 1990s. Even estimates indicate that eGold was bigger than BTC in both capitalization and users but it wasn't really covered as much in the media.
Bitcoin got a lot of attention because it made a lot of random people millionaires. Whereas, nobody got rich off eGold except for the scammers and hackers. The media loves that rags to riches story..
Block size is still 1 MB.
Bitcoin is still an experiment. I think it would be very risky to achieve an adoption at WhatsApp, CandyCrush or even Telegram levels at this moment. Also, all these platforms are centralized.
Even more, Bitcoin is not just an end-consumer product. To being functional as everyday money, it needs to be accepted by merchants. And this is a slow proccess. It doesn't have commercials on TV. It doesn't have the "hey, I'm using it and you should use too".
Just to compare, even debit and credit cards still didn't get an universal adoption. Here in South America, there are a lot of informal and formal places which don't accept them, they only work with physical cash.
