Sometimes the best way of understanding a trend is to observe the opinion of the people surrounding you.
Let me give an example.
I spend three months on Santorini in the summer of 2016 and despite many prognoses where suggesting a bremain, I spoke to so many English people that were supporting a Brexit. I then ignored many of the mainstream news and was more than sure about that the final result would be a Brexit.
Somehow I have the same experience now with the cryptos.
Recently I heard many people at work talking about cryptocurrencies, not only Bitcoin but also several altcoins. This is for me a serious indicator that proves how the cryptos slowly but stable are becoming mainstream. Personally I believe that the development of cryptos will escalate once even more people realizes that Bitcoin only is one cryptocurrency and that you can select the coin and developers you trust the most.
The mystery of Satoshi Nakamoto did in my opinion not allow the cryptos to become mainstream, but now that people can invest in a coin that real people have created the main fear for investing in Cryptocurrency is gone.
It is all about the coins now!
We are reaching the point now where cryptos are normal to talk about as a mainstream topic, and I think that this is why 2018 is going to be really wild for the cryptos.
