You may also include traders who tend to trade a lot. As the market condition is quite bearish or the volitality is too high, they need stable coins such as Tether for their exit trade; these stable coins are keeping them losing for such market that is unfavorable for them.
I think a lot of people who are interested in investing crypto due to rapid market movements, and not price stability. they are investing to take advantage of the rapidly changing market conditions, because that way they can get a greater advantage and quickly.
probably because until now the role of the crypto most only as an asset investment, not as a means of payment. When crypto is used as a means of payment is of course the stability of the market price should definitely be noticed.
