I posted a new article today, this time not on Cardano (though relevant for Cardano) but on the more general topic of what gives cryptocurrencies value. It basically describes how money currently functions in our economy and how cryptocurrencies attempt to change that. I particularly attempted to write it for people that are new to the cryptocurrencies space, I hope it could be a good on-ramp for people. 
NB: The article is also available in Russian thanks to @timsahabutdinov
