Samsung S10 will have an Eth wallet by default but not Bitcoin
The eth wallet will of course let people get access to their ERC-20 tokens as well and there's still not fully confirmed rumors that the Enjin Wallet will exist in the "Samsung Play Store". If you have any confirmed sources about this then feel free to share as I am having a hard time finding any. There will also be a few more dapps supported by the new phone, you can read more about that in this article
That's kind of a funny choice. Wonder why they did that. Maybe they're gonna release an ERC-20 token? Or do something with Etherium?
