Which shows that ONLY the countries listed below can link to Uphold or Gemini. All other regions are unsupported.
Unfortunately Malta left the UK long ago and, even though it’s near Italy, you’re an independent nation. So yeah, you’re able to use Brave Rewards and earn BAT but you are one of the places that currently is not being supported in terms of linking to Gemini or Uphold. And to make sure you’re not confused, this is a decision by Brave as they are working on issues they were having with regulations and fraud around the world. They said will START bringing back other countries in about 2 months, with France and India being among the top priorities.
