You are holding a call option, meaning you have right to buy, meaning if you exercise now you have to part with your cash now.

If option is deep in the money, then it is better to exercise it later rather than now. That way you get to keep your cash longer and earn discount rate on it.

Always, other things same, it is better to
a) buy later rather than sooner
b) and sell sooner rather than later

Hope this helps.
