Profit on Coin Listings

Hey, everyone!
I simply started collaborating within the itemizing of latest coins, hoping to buy it as soon as it's listed and sell on the pump. I purchased LA and ERA and had some profit dispite a couple of beginner errors that I did.. but on C (Chainbase) I had a bizarre loss, the worth principally was only pumped for 1 second (literally) and then after this the worth was simply taking place and down, so I made a decision to 'stop loss' and bought it

Anybody knows why this conduct? Is there a pattern? Do you've got any ideas for me or is it just a huge gamble? Thankss!
