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.
See this bullish market has been very much effective in attracting more investors in the crypto into the crypto market as a result of which the influx of money/credit in the crypto market has dramatically raised exponentially. So yes there occurs some good correction every time we see a surge in the market value of crypto.
