I don't think that BTC is unfair towards the non tech--savvy. The non tech savvy can just understand the economic concept and the concept of how BTC is a currency. Rather than understanding the Blockchain and the Algorithms behind it.
Exactly, IMHO those who see the long term potential of bitcoin generally do so more due to understanding of economics and how governments manipulate money than due to mathematical savvy.
People who see and question the government intervention and corruption tend to latch on to bitcoin in my experience. Those who don't will one day just complain when btc reaches the moon.
