In my opinion one of the reason why cryptomarket fall is ourselves the owner of the crypto. We too sensitiv with news that exists, so it appears a little bad news about crypto we instantly panicked and chose to sell our crypto. So from now try to learn to think positive that world crypto will persist in the future.
I agree with your opinion, the crypto market fell due to negative sentiments from various parties who disliked bitcoin getting bigger. Bitcoin can be a currency that is used throughout the world because of its simple way of working, peer to peer, the role of banking is declining, so the government cannot control the price of bitcoin. So a lot of negative sentiments were exhaled so bitcoin holders panicked, then sold at falling prices.
