I also agree with your opinion that we should invest in altcoins that have been able to survive in bull and bear markets. and these coins have proven that they always experience ups and downs in accordance with market trends. and I agree that we should not exert energy on coins that do not have a solid foundation.
All these can be known if you are only taking your time to study the market, and if you are also good in research before investment, and all these can be achieved if you have knowledge about what exactly you are about to do.
Crypto investment is risky especially altcoins, you will have to risk your money to invest and some projects will have anything a good project needs and they can still fade out and go with investors money, while some projects you never think will do well will end up given huge profit, but if you follow FOMO, you will fall victim and lose money.
As a newbie in crypto, do not rush to start with altcoin investment despite the coin’s performance during the bear and the bull market because people might have been done with he project. And also know that early investment in newly promoted projects is good but very risky because you can make huge profit if the project favors your, and you get bankrupt if you invested in the wrong project.
