1. Venezuela: At first Bitcoin mining was illegal but since January of this year the president Maduro declare it legal[2], this country have the cheapest electricity in the world, it cost $531 to mine 1 BTC so is very profitable. Most of the internet companies are not so good but there are a few good companies that provide satellite internet that can solve any internet connection issues for an incredibly low cost. The only disadvantage is that you have to bring your machines from United States, Canada or China and do not need to worry for the economic crisis since you can easily pay high qualified workers 100$ per month or even go to 5 start hotels for 20$ per night
It was never illegal, but police is very corrupt and can do things at random that has nothing to do with the rule of law. In theory, the gov welcomed it starting 2018, but some people were still seized equipment and put in prison after that, because... The corrupt cops would fabricate lies such as money laundering, funding "terrorism" (as in political opposition groups) or what not, to the victim that refused to pay whatever they were extorting.
As for sending machines, they were being seized for the major part of 2018. I'm not sure if you currently can or cannot bring them without risking seizure, I have read conflicting reports. Some bring them in parts hidden among unrelated goods, some just use DHL, I don't even know anymore...
Venezuela has frequent blackouts outside of Caracas, and in Caracas itself sometimes electricity fails. This is not due to lack of generation, its due to lack of maintenance (a by product of hyperinflation and price/currency exchange controls) The government officials stated that they would like large miners to set up operations at the southern State of Bolivar, close to the hydro generation, or in industrial areas in Carabobo or Monagas States iirc.
Crime is super high in this country so if you ever think of coming, you have to look and act as poor and plain as possible. Certainly NOT use 5 star hotels or bring luxury things such as any Apple products, jewels, gold, etc.
