which type of current do we use in our daily life?
electronic current or conventional current?
a correct answer with accurate explaination will clear my doubts and I will be so thankful for that.

Conventional Current
Conventional current is not an alternative “theory” for current. It is just a shared way of talking about current direction.
The definition of current is short and simple,
Current is the movement of charge.
This simple definition gets interesting because electricity is two types of charge, and they move in opposite directions. If negative charge moves right, then positive charge would be move left.
This “two types” property isn’t something we come across in everyday life. For example, there is only one type of mass, and if we have two masses they are always attracted to each other, never repelled. Electricity isn’t like everyday life.
Another twist: The instruments we use to measure current (ammeters) can’t tell the difference between current caused by positive charge moving one way from negative charge moving the other way. An ammeter can only report a single number when it measures current, so it gives us one number for the combined amount of positive and negative charge moving around (see the definition of current).
We have to make a choice about which way to indicate current direction (the sign of the number on the ammeter display). The convention (the habit) we use to indicate current direction is to say positive current is the direction positive charges move. We use this definition even if no positive charge is on the move. With this convention, the current arrow points in the direction negative charges (electrons) come from.
The term “conventional current” sounds like it may be a new type of current. It would probably generate less confusion if we always said the longer “conventional current direction” with emphasis on direction. Whenever you see “conventional current” it is referring to the definition of current direction.
