The market has been attacked by banksters, cartels, and central power and this creates a lot of FUD in the space. People are influenced by those events and panic sellers, weak hands, and speculators remove their money from the space.
Then the whales and people with a huge capital increase their position and repeat the cycle.
Do not panic and HODL!
I agree these are the problems cryptocurrencies will have to face and with more FUD being spread every day the market keeps bleeding because people are now paid to bring fear to feed whales cheap coins or influence people to pull out but this cant go on forever as its an expensive operation.
