Both bitcoin and altcoins are going to see increase during 2021, but don't get carried by the hype train, they will still fluctuate, but something almost certain is that they are going to become stronger while the fiat currencies are going to get weaker.

The issue is not really what countries are blacklisted to receive bitcoins, but if you have a way to withdraw the funds on a way that works for you.
Bank, AMT system or equivalent, if not, you need to figure out a way to make use of those bitcoins online on a way that is relevant to you.
