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.
