If our bags are still loaded and we have many of such outdated Altcoins, we sit already at a loss. But we should prevent to get more loss by selling our bags and exchange it to a more reliable (Bitcoin) or innovative (Ethereum, Avalanche, Algorand) coin.
You are right we shouldn’t have too much on our plate. Having so many altcoins does not increase the chances of you getting profit especially if you just mindlessly picked them out.
I also agree that we should leave outdated altcoins behind however we shouldn’t confuse old with outdated. Some altcoins have been in the scene for a long time but are still actively developing and improving.
And next time, we should always review coins to prevent a loss. When a coin is reviewed badly by experts, like Tron and EOS have received bad reviews by experts, it is time to sell quickly.
Sometimes experts would have clashing opinions so it’s best to understand
why a coin is good or bad so you can make your own conclusions and not just rely on what other people is saying.
Yeah, making your own decisions and analyses is essential to start getting ahead of others and thinking into the future a bit, knowing the pattern of some coins because of some prerequisite. It's just more convenient because you wouldn't be dependent on anybody's thoughts, and your profits or losses would be in your own hands.
