I don't know what is 'good' indicator...
So, I can make two option of good.
Yes, cause the tether price based on real USD price, so price is very stable. And you don't afraid your tether will dump. And you can use tether for backup your asset.
In before point I've explain about tether price character. And yeah very stable, but to make profit, you will not generate high profit to trading tether.

The conclude is tether will be backup your asset cause the price is very stable. But not recommend to trading.
