I am not saying that I want to buy expensive ones, I only dare to buy when the price of Bitcoin rises. Although I know to buy low and sell high. I don't know when the high is. I also generally don't sell my bitcoins. I feel safe looking at it in my wallet. I will probably sell when the cryptocurrency bull market comes. I know now is not a good time to sell. Now is the time to buy.
That is really the point of OP, newbies can only notice it when it is in green days or at high price since newbies thinking that it keeps rising but the problem is that that is already its peak so it will go down again . Also on red days you keep thinking that it be going down so you will not buy again. Though nothing is wrong at buying at high price but newbies tends to rant in social media about it and also they don't do their own research. Try to understand more the price action of bitcoin so that you will know when to buy or sell.
