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.
Yes true it's better to hit and run, even though we love it but when loss the coin doesn't care. You say don't put all the money into single coin, that means we have to put it into a few coins. Isn't this way just going to make confused? because there are too many coins to monitor. On the other hand, if the price of all the coins goes down simultaneously will loss more.
