buy when it goes down and less quantity if it continues to drop buy more to average a little lower the price

I have been tracking Solana for over 1 hour, even longer when I see it rising, and every time I buy, it stops, and not only that, it starts to drop, and it is always like this. My question is whether it is sufficient reason to suspect that exchanges put custom spyware on each user to take their money ????😱
