To me there is nothing to feel sad about because I already have the knowledge how the price is being manipulate over some times so seeing bitcoin dipping unexpectedly won't warrant me to start panicking over time, we know there are things possibly to happened which includes price increase or price decrease there not above this to happened. Whenever an investor already have this knowledge I don't think s/he will have to panic over the price rather would sees it as opportunity to accumulate enough volume of bitcoin to add to their portfolio.
That's right. During the spot
ETF adoption - I think everyone has seen the
SEC manipulation. What they were doing was nothing but laughter.

Believe me, there will still be (many situations) in which we will be manipulated. + Don't forget, any manipulation by the
SEC is a squeeze on funds.
P.S. When exactly to buy/sell is as individualized as possible. I will not advise anything. It depends on your goals and how much you want to earn on this market.
An interesting statistic came to hand. "
The number of unique addresses containing at least 1 Bitcoin."
