The fact that the wallet is limited only in certain regions is what makes this wallet lacks the attention of the crypto community. I do honestly own S10+, when I first heard that S10 have built in wallet I kinda feel pumped though after that only to bedisappointed with the fact that the wallet limited to certain region. Regarding the addition of BTC, I too just don't have a clue about this, maybe they still not be able to create a secured bitcoin wallet?.
Hundreds of development groups have come up with Bitcoin wallets that worked just fine. I presume they feel the future lies in other coins but that seems like a very, very strange decision to me.
Then again it's Korea focused and Korean crypto tastes seem deeply fucked up to me. Any country that has a higher trading volume in Bitcoin Gold than Bitcoin for periods of time is clearly filled with nincompoops.
Is there a list of territories where it's available? There's been so little mention of it I can't tell whether the wallet really is Korean only or not. Some elsewhere have said they found it when looking at available Samsung apps that you have to download rather than it being there waiting.
