and they ‘cannot’ be used in the same text when the situation favours currently,it is not that presently cannot be used but it is that currently has a far more advantage of being appropriate for certain texts,for example the example u gave ;in this case ‘We currently live here’ is most appropriate because ‘living’ iserves over a far more period than instantaneous moments where presently would be most appropriate.

Currently can be used for farther ranges in terms of time than presently which was stated above that it is used for more instantaneous moments.However presently can be also used for longer periods of time when comparing large measures of time such as decades, milleniums etc.
