If we're talking only about trust, then yes, I totally agree with you. But let's not forget that we also like to money so regarding that, I think there are coins and tokens with more potential growth compared to bitcoin, that already has a very big market cap, so it required a huge amount of money injection in bitcoin to make a 2x or 3x while some altcoins can easily make a 10x.
Some altcoins are more profitable than Bitcoin and their success is huge than Bitcoin but you should also not forget that they are not more trustworthy than Bitcoin therefore people often choose Bitcoin as they don't want to put their money at risk and lose their trust plus money.
Altcoins are many therefore you have to completely concentrate on trustworthy coins and among thousands of altcoins it becomes difficult to choose the right coins therefore choose either Bitcoin or top altcoins which will provide you slower profit but that will be sure.
There is no doubt that certain low price altcoins make you able to give you huge profit but that is not guaranteed always and you have to dive into such risky investment if you want to get huge profit faster.
Most of them are pump and dump then after we see those 1000% up or more which people want to see for sure those huge dumps will follow and those coins will usually get a hard time to recover. That's the risk of acquiring those alts especially if we got FOMO since for sure with that we will became their bag holder. That's why if they want to focus on long term holding then they should never look at those altcoins especially those new since the only thing they can get is to be scammed. If they go directly with bitcoin for sure that there's a good destination with their money and effort spent since bitcoin always prove that good profits are always given to those people who have good patience to invest their bitcoin for many years.
