Am I missing something here, they can be worth billions and already are. Facebook's market cap is about 450bn and cryptocurrencies as a whole is at about 300bn, that's only a 1.5x difference. I think comparing crypto to facebook is a strange choice because they're very different but if I had to I would argue it actually shows cryptos to be a little overvalued just based on numbers. It's very incorrect to draw such conclusions because they function so differently and so their values should be very different.
I think it's not accurate to compare one social network and all cryptocurrencies. And I think that main difference is a numver of users. If I'm not mistaken, Facobook have more than 2 billion registered users. How many people are using cryptocurrencies? Not sure, maybe tens of millions. Just imagine how much Bitcoin and ofher cryptocurrencies would be used by, let's say - 0.5 billion or 1 billion. Then only Bitcoin without other cryptocurrencies would be worth more than Facebook. And there is another thing - after recent scandal, Facebook are loosing it's value.
Not at all, or even just to bitcoin. Facebook is far far bigger in terms of global reach and influence. More than anything I think it just shows that market cap is not a great measure of the size of cryptocurrencies.
Somehow , bitcoin or crypto currencies and Facebook have different functions anyway. . Obviously , that the owner of Facebook is a billionaire as he counts the users , almost all people in the world . In cryptocurrencies just only those who knew it. So we can not be sure of the counting , that small difference is inaccurate thing. Besides crypto currencies or bitcoins users could Help Facebook and Vice versa. Maybe when crypto Will be introduced well to the people and Its growth Will continously for the next generation to come, it might overtake also the value of Facebook. It might as well have additional kind of social media at that time.
Entirely different, it's why they're so incomparable. If bitcoin can ever get close to the number of users that facebook has then it would probably be the most used currency in the world and $8000 would look like an absolute bargain. I'm sure eventually facebook will integrate some form of cryptocurrency but I suspect it may be their own.
