Should I learn coding or just hire coder? I already have $1million.

I've already have a business(not tech), I've got $1m.

Now I want to start tech business like develop iPhone App,
make SNS like Facebook or twitter.

so now I'm studying coding like javascript and PHP,
but sometimes I feel like wasting of time.
Because I already have money to hire coder, so I should focus to manage them?
As an entrepreneur, I have to hire coder instead of studying code?
someone says you have to be manager not coder.your work is to manage them.

but also I think I have to master coding.
because many successful entrepreneur in tech company,
almost all of them are coder, Facebook,Twitter,Google,etc.

so… which is better choice?
