I don't know why, but if you give me a guide I'd appreciate it.

I buy a currency like for example #XRP.: that is at 1.90 and it looks like I bought it at 2.40 or #ACT that is at 0.39 and it buys me at 0.45 and so on, because what is the reason? I have noticed it already with several that I enter to buy and buy with a loss of certain points above the current value.

Could someone explain to me why this happens like this?
