Actually people's learn from mistake. Those mistake I did began, I am realizing now. That's why I want to share it. Perhaps everyone will not agree with me. Every traders have few favorite coins. It's normal fact, but don't love too much any coin it's my logic.
I don't want to mention but I have lost many btc just one coin. Just think it will go more up and didn't sold. In a result price dropped 4X. So I want to say don't love any coin, just sale when you are in profit and go another coin or wait for drop price again and buy it. It's very difficult to recover once drop an Altcoin. One more thing, don't invest your all fund on single coin. It will loss more, who know it will up or drop.
2017,during the last bull run, I didnt lose anything. When the price got very high to $19,500, a lot of experts started predicting that there will be a fall. Though I was a bit greedy and wanted to continue to hold cause I believed that the uptrend will continue, but I changed my mind and decided to withdraw and after I did that, the market began to collapse. Bitcoin is always my favorite, but I still trade altcoins.
You as so lucky that you win at the end and you did not lose anything. Those who become greedy and dont sell anything on right time they will be sad later in future. I love bitcoin too because its reality that bitcoin never give you any lose until you make foolish mistakes like panic selling.
