Over the past three months, the capitalization of the cryptocurrency market has decreased by almost 40%, and the largest share falls on Bitcoin. This indicates, first of all, that cryptocurrency users are afraid for their money and get rid of Bitcoin because they lose confidence in it. Negative feedback about Bitcoin regarding the scaling and relatively too expensive mining, which is becoming unprofitable and inappropriate, is constantly heard.
In my opinion this sudden price movements are not coincidental - it looks like straight up manipulation from group of big players. Negative thoughts about scaling and inefficiency of mining are presents since begining of BTC so this can't have that big impact on market prices
