$BTC Trading with emotions! Yes, because nothing says 'success' like buying a coin named 'DogePepeInu' just because its picture is funny.

Tip: Don't trade like you're watching memes, the market is not Instagram.

The second mistake: Chasing peaks. Did you see the price of Bitcoin rising? Great, let's buy it now that it has quadrupled! (Then we look at the ceiling after the crash and think: 'I should have bought it when it was cheap').
