Crypto isn’t a Brave issue. Uphold and Gemini are restricting regions, such as how Uphold just pulled out of Venezuela.
There are a LOT of government regulations that are controlling what can happen in the crypto world these days. Brave is working on other options to try to be more decentralized again, but it’s not easy or quick. You’re still able to earn BAT, tip Creators, etc. The only thing you’re limited on if Uphold and Gemini aren’t allowing Brave to connect in your region is that you can’t convert it to cash.
If you get time later, check out Psa: updates from brave call
In that is link to YouTube to hear them speaking about it a bit, especially if go to where I started talking to them at around 42 minutes in the video.
And as I said, where it’s not all Brave, check out PSA: Venezuela no longer supported by Uphold (or Gemini) and the comments there.
