being a bitcoiner does not need a fast internet or a high end gadget because what matter the most here is your knowledge and decision making .
other countries nowadays are now have a fast internet connection because of the adoption of 4g technology but even 3g connection can still be useable whenever you access the internet to do your crypto activities .
aside from that , do you think you can understand other people if you move from a country that you arent familliar with ? not to mention the cost and overall expenses , thats why i think that is a bad idea .
