I guess there is a lot of news that could be correlated with the drop of Bitcoin and Ethereum, but I believe the most important one (not mentioned here) is the launch of IOTA. IOTA has reached $1.5 billion marketcap being in the top 10 crypto currency, and it threats all altcoins by its non-blockchain technology known as tangle. I believe that's the reason for the FUD and red markets today.
What does that have to do with it? Russians have developed some serious stuff over the decades..
I just do not trust Russians and i do not invest in Projects "Made in Russia". I'm myself also a Russian, and i know very well Russian mentality. This is just my opinion.
