Zoom? For someone to “zoom” past you, they’ll need to spend $24,000. LOL. I sure 99% of the forum members here spent <$10,000 on Anker products. Probably even <$1,000. So really, we’re talking a few hundred XPs. No one will be pooping on you. That’s just paranoia.
I think 1 PB is enough. For both XP & PB, they are meant for “light-hearted spice” to add “community morale and interest” when you make an Anker purchase. Neither is meant to give you a substantial advantage in leveling up (you won’t) or being able to dominate a PowerDraw (you won’t).
Anyway, I’m sure Anker overlords will do what they think is best. Neither XP nor PB will have a significant impact on anything unless someone spends tens thousands of dollars … and even that can be curbed by limiting this to 1,000 XP/PB per year.
