I guess only time will tell. There are several Bolt owners now with over 200k miles, with not much over 10 percent degradation. I think it all comes down to the charging profile and the thermal management. I will use DCFC on mine on trips and times when needed, however I don't have any options near me either. I think it really boils down to how much you care about degradation. I will do the same as I did with the Bolt, charging to 80 percent daily, and limit fast charging, as I plan to keep the car a long time.
