Indirect cell reference

I what to make a cell that contains another cell ID. I want to then use it indirectly in formulas.

For example, I want to enter $A$21 into cell B2. Then in cell C50 I want to enter =(indirect)$B$2 and have that be the same as if I had entered $A$21 in C50.

Is there a way?

You nearly had it:

=INDIRECT($B$2)

Hope this helps.
