Many of us believed that the bear market is officially over already and the bull market has started. The correction that happened yesterday doesn't mean that it will not rise again. Its better to have a correction after a continuous rise compare to a market that is only rising and rising and rising. See what happened in 2017 & 2018.
Yes, the sudden increase will always lead to making some corrections which help to reach another milestone in the coming days. Everyone is expecting we are in the bull market but i don't consider it suddenly happen because slowly the price of Bitcoin and other altcoins will start increasing in the market.
It was not a slow process but a sudden one and it all happened in a range of 3-4 days the Bitcoin jumped to 8k dollar figure while Ethereum to 270 US dollar figure. But the prices have declined since two days the prices are stable at 7315 US dollar for Bitcoin while 236 US dollar for Ethereum. This stability after the decline does not mean that the coins will not increase again but we should stay calm and observe it.
