Gamesharing and in game currency

No. In-game consumables will only work for the account that purchased it.

He's a friend of mine who moved to the UK...We used to play with each other until he moved to UK but decided to just not reset his home Xbox..

Which is why we are gamesharing…

I did not mean sharing virtual currency..

I would like to purchase virtual currency on my own account...But his account region now is UK and mine is US,,,

I was just wondering if it will work...I will be purchasing virtual currency using a US account and play the game which is owned by the UK account using the US account...I was just wondering before I make the purchase if the virtual currency would still
appear in-game even though my region is different from the game's owner?

Account specific items may not be able to be shared. Some examples are:

• In-game content purchased within the game with in-game currencies like Minecraft Skin Mashups or Halo REQ packs
• In-game currency such as Minecraft Coins

Certain pre-order bonuses and special edition content falls into these categories, so you may not be able to share those items as they can only be redeemed once from the account of the person who purchased
the game.

When you gameshare a game, in -game cosmetics bought on a certain account will NOT be gameshared, this applies to certain DLCs too.

No. The currency would be tied to their account since they purchased it and would not show up in your account at all.

Also, just a heads up, if you gave each other your account information in order to gameshare, that does violate the code of conduct and you would be putting yourselves at risk for being banned.
