My experience in trading that leads to loss some of my portfolio is when the first time i buy some of few altcoins in a high price,because thats time all the crypto coins is in the highest price in crypto market,because i have no choice that time and lack of knowledge about digital currency bussiness,so when the time the consecutive drops of all altcoins is coming because of price blow off i panick and FUD in all my investment,so in order to prevent lossing all my asset,i sell it in a low price,so that i recover even a half of my capital,but now i regret that times,why i dont hold it until now,because all prices now back to green.
