You can't blame them, cause most of the times it's difficult to really tell which coin is going to do well and which one is going to be bad. Everyone is being very careful and don't want to bear the loss. They feel its better for them to sell those tokens and use them to buy ETH or BTC and then save with those ones. And another thing with these small tokens is that you might think that they are growing and wouldn't know that they are just getting pumped and will be dumped within a short time. Although I do know that cryptocurrency is all about taking risk, I would suggest that you only take the risks that you can take.
