Hi all,
Cryptocurrency market capitalization presently is around 115 billion USD.
Market capitalization of only one social network site Facebook is around 435 billion USD.
Cryptocurrencies usage is expanding in my opinion for sure in more intensive pace as Facebook. So I think that there is potential for market to grow by at least 3-4 times in a foreseeable future. Additionally just look at Facebook market cap history and 3-4 times might look very conservative.
So lets see how things will develop further...
