Both PTS and AGS will be honored by all following DACs, including BTS. However, AGS can not be traded, which means the performance of 3I will definitely affect the value of AGS. On the other hand, the value of PTS also depends on the performance of 3I, doesn't it? Be aware that now you can get more AGS by donating same amount of PTS. To this point, I would rather get as many AGS as possible, if I want to hold PTS for long time.
