Really hard work and big goal my friend once i got bitcoins i will become rich bitcoin cost is increasing day by day. with in months we never expect how much increase this.
I think keep Bitcoin in the wallet is a smart way. The price of Bitcoin will continuously go up, higher and higher. Wait until the best suitable time, sell it, a very very huge money you get 
I myself use Bitcoin to pay for my cost of living and my school fee to the University too.
