When you are a citizen into those countries which do impose up some bans or restrictions then you would really be finding this situation to be hard but it wont mean that you are totally being get rid of for you to avoid or being restricted on dealing with crypto.We could still make out some engagement though but it wont really be on the sense in full scale or totally free and once you do decide on dealing still with it
then you should be careful because you do know the risk once you get caught.
This is worst if you are caught then you have to face some serious issues not only financial in many other ways as well because it's already happening in few countries where crypto is illegal they are giving them long term prisons fines and having their all assets as well because few months back I have one friend who was caught then he lost some good amount and until now facing some serious legal issues as well.
If some country banning crypto then you have to follow rules very carefully because this is not easy to do this all under this judiciary. Sometimes they have fake traders or things like this for having all updates about these crypto related peoples.
