The cryptocurrency market has always been quite small. After ~three years of devaluation of coins, we are now beginning to see the utility of these technologies and thus the aborption of bigger market caps. Coins have been undervalued and the market is now correcting itself. I think we are going to see massive growth.
There are only 21 million bitcoin. Not enough for every human. That puts the value at millions of $ per bitcoin once cryptocurrencies are fully mainstream.
Incredible to imagine if that day might come. Such a thing may take decades.
Mainstream by 2025. I think we will see maximum increase in values over next 1-3 years, then the volatility to start easing off as more people adopt it. Bitcoin recently became legal tender in Japan. There are lots of big things happening in 2017.
