Common mistakes of those newbies in trading are being hyped and excited about the profit they are seeing when they see advertising or influencers that are flexing their earnings from trading. They think it is easy as that without knowing that those influencers or ads don't show the hardship or grey part of trading.
Well to be precise they stsrt buying when they see the post. But they didnt know is the influencers probably bought that when its on the red line and ready to pump their bags. Newbies who followed and started to buy will be an exit liquidity for the one who posted. They will noticed that when the influencers starting to be quiet about that project means they already profited from you and you saying thank you and making an engagement on the post also added on their revenues. Tsk a world of deceit and manipulations.
