Why is this so common with newbies more especially those that doesn't know the principles of the market. Could it be they are not confident with the price then or wanting to see some changes before they could go into it or just can't say.
I could recall a friend of mine then who have been wanting to invest in bitcoin which he always calls to know the dip part of the price so he could buy some fraction of it, whenever he calls, i will tell him yeah you can buy now because is at a good point were you could buy some reasonable fractions. Do you believed that he never took it serious till bitcoin gain back momentum then, lastly what he did was to say " Let me buy now before i would be left behind" and he did, surprisingly the price dropped, but i advised him not to sell rather hold.
You shouldn't wonder at all. Well, as a newbie your knowledge is still limited so are extra careful on the steps that you will take but there are also newbies who are reckless at the beginning. They are more on the FOMO side. What happened with the case of your friend is slightly different. If what we have earlier are newbies who are less confident, your friend here seems to be a veteran already and is over confident with his ability. He also waits for the dip instead of the pumps. What could be your friend's reaction by the time he fail? Not only once but twice.
It would be great if he admit his mistakes and will now learn from your advices the next time. Not that he still blame you and thinks it was your fault on why he got a bad luck. I know a person who act like this.
