Yes thats true new altcoin is a great way to earn some profit but it is really hard to do nowadays because you need some time to monitor the movement of its coin, with some slight miss you may have chance to get low profit or may be didnt have chance to get the profit. Need great experience to make sure you will get profit from altcoin
Betting that a new altcoin will have a good pump after being dumped by the obligatory initial dump of miners as soon as a coin gets listed in an exchange = total lottery. Sure, you can try to guess what is or isn't worth it looking at the features of the coin, but at the end of the day it all comes down to what the whales are feeling like pumping.
Yes I know that is good things to do, but it is not easy to pick or are you saying to get more than one random altcoins then try to hope that my picks will be pump? Is that so? Actually it depends on whales, how can we predict which altcoin will they pump? If we can try to guess it I think its ok to get altcoin if not better not try to or later will lost all of your bitcoin
