In my opinion bottom has not been reached yet, I see 3500, 2500 and 1500 as realistic short term stops for BTC.
This hell of volatility will only be a thing of the past, if legal concerns are wiped out on a global scale and proof-of-work has to be left behind as well.
In every market/Trading there will be ups and downs. Especially for BTC the investors or some groups manipulating the price to go down and buy lot of coins in lower price then increase the demand of coins and earns huge profit is what they are planning. The price of the bitcoin dropped sharply because of the recent bitcoin cash fork. Hoping for the best to come in upcoming days.
