I have no idea why people put word blockchain in everything, it looks like blockchain is a magic word that's used instead of Abracadabra, I wouldn't even be surprised if magicians say Blockchain while doing tricks. I think that increase mostly comes from former Soviet Republics because in these countries, a lot of people don't had access on PC and internet, there was DSL in most of these countries for a long time and we can say that fiber is new for them.
Also in some countries internet is expensive but at the same time there is a huge bandwidth usage because of pirate websites (multiple upload of different movies, games and etc for each website).
