学习缅甸语的好少

ကၽြန္ေတာ္ is used in formal setting, as well as when you want to be more polite. so, it's safe to address yourself as ကၽြန္ေတာ္ when you are not sure how to address yourself. ငါ is for speaking with friends, people younger than you in informal setting. က်ဳပ္ is more commonly used in rural areas, some people used it when they are being sarcastic.

ကြၽန္​​ေတာ္​ is the best choice to use when you speak with the guy who is older or younger or same age as you. ငါ is use only with your friends. က်ဳပ္​is not very common today but still use in older people's environment.
