It's not my intention to make an advertisement for the Weiss Ratings and all the stuff they offer, but I recommend to read Juan Villaverde's new article about privacy coins:
https://weisscryptocurrencyratings.com/news/war-cash-part-2-risks-privacy-coins-1187
He is expaining in this article why cryptocurrencies are important and how they could help to stabilize the financial system.
The second part explains why privacy coins are important because the total transperancy of the blockchain has also negative sides (for example in malicious regimes).
It's an article definitely worth reading!
Please upvote and resteem to help me spread the word about cryptos! Because it is probably a cheap entrance state at the moment for Mann interested people.
