What has stopped the fruit sellers from using bitcoin to avoid sanctions for the past five years?

[toolz]

It hasn't stopped them or anyone else, people have been using bitcoin to bypass censorship for years.

Then why are they still "suffering immensely" if they can already use bitcoin to bypass the sanctions?

[toolz]

There are people bypassing sanctions with bitcoin that aren't suffering as much because of it.

As for why everyone isn't using bitcoin to bypass? Good question.
