Research is suggesting that the number of ransomware incidents has risen in 2019. The payment method of choice for the majority of this cybercrime is cryptocurrency, predominantly bitcoin. Could BTC price fluctuations be linked to the increase in this online nefarious activity?
https://bitcoinist.com/could-ransomware-be-driving-up-bitcoin-prices/I don't think people paying in BTC is enough for the price fluctuations we see today. Besides, the price today isn't really doing good. The OP has a point but I don't think it's enough factor that could drive the price up. It's still mainly by whales, or by trading which is primarily affected by news and such. I also don't think that it would do any good even if BTC is introduced to innocent victims via these ransomwares, because most likely, the victims would remember BTC in a negative way, as used in illegal activities.
