How do you guess bottle caps will be obtained for Hyper Training in S/M? They'll no doubt be a bitch to collect.
BP, probably.
They might have a pokemon that naturally holds bottlecaps (like Luvdisc and Heart Scales) or they might randomly wash up on some beach like the feathers from B/W.
>>27401249 is also possible.
Gonna guess they are a secondary currency like Game Corner Coins or whatever and will be obtainable by playing minigames.
Or they are this region's equivalent of BP, in which case I really hope Battle Spot will give out BP.
Go away, James.
>yfw they can only be obtained in Pokemon Go and have to be transferred over through some process that requires a monthly fee
