Corrections are a natural thing in the crypto market, and usually after bitcoin reaches ATH we see a correction. I don't know if it is manipulation by whales or it is a market habit that always experiences corrections after reaching its highest point.
We can take advantage of that time, using our money to buy at a low price during the correction
It's not market manipulation, it's the nature of the crypto market. You know that crypto market is drive by speculations and hypes, when we see that something is coming, we build hype on it with promises that Bitcoin will do this and that, its has been the custom tradition of the market for long and when the hype is no longer visible, the smart ones exit before the rest exit the market.
This has always been what crypto market does most of the time, the market is build by speculation and the hype, that's why correction do comes after the news. However, this season has been somewhat different from the past ones, the market is bullish and people are still having some bullish about it that's why we haven't see correction yet.
