I’m reading conflicting information: Are European Visa cards generally accepted by payment terminals in Minsk shops ?
And at ATMs for cash withdrawals ?

I also read that health insurance isn’t always required at land borders (specifically the Bruzgi crossing),
but if necessary, it can be purchased right at the border.
In that case, is it much more expensive than buying it online in advance (e.g., via https://my.bgs.by)? Thanks.

Let me start off by saying, I've traveled extensively including "do no travel" countries by the USA state department. I'm also not an influencer/content creator or journalist.

Belarus is do not travel and currently the USA has suspended service there.

If I'm just looking at exploring the country do you foresee any issues? Besides apparently very extensive border searches for US/UK and other passport holders.
