Didn't you know that those people who have limited assets or funds are the ones that usually good at trading? The reason is, they are eager not to experience any losses as if it happened, it will be hard for them to recover.
Those who have more funds, they are just ignoring the fact that they are losing more since they afford to lose that amount. Since they afford it, they are not aware that those losses are now turning into a big amount.
People who hold a different coin is too much exhausting because you need to check those markets every time unless you really have a lot of time and effort to it, its more ideal to get at least 3 coins you need to focus and makes an investment if you are heading to the long term ideal to have many than that but if you want to have a short term try to make an investment to a specific coins even though altcoins its profitable not only bitcoin.
