Not understanding the market.
If you lose your own funds in crypto, you will be afraid of investing in crypto.
Uncontrollable emotions, emotional investment.
Follow the giant whale trading blindly. Believe some media reports.
Distrust of coins.
Relatively greedy and impatient.
Newbies are less patient waiting for the coins they buy to go up. They don't know when is the right time to buy. Most of them buy when the coin price has gone up tens of % while they sell when the coin price drops. Whereas when the price goes up, it is the time to sell, while when the price goes down, it is the time to buy.
