Buy my self a beast pc with gtx Titan and i7 extreme.

Also, convert the rest to steam wallet and go on s spending spree on steam.

Well , that was too bad to think for a long term .its a big mistake or a bad idea when it terms of holding that kind of money .best thing ti do is to think for tge long term how can i make it grow .

You should've given me that at the time you've posted this, I'd wait until the price reaches it's peak and sell all and wait until it goes back to $300 or so and return your 10BTC back

Maybe you should just keep them until the price increases? if you were to give me 10 btc i would totally waste them on goods i would like to buy tho. or "invest" them on my college life so that my parents won't have such a hard time supporting me.

it is my desire to start a business where  i will accept bitcoin and will do transection and exchange in bitocoin. but actually in my area most of the people do not know about bitcoin. they are unaware of it. they need a lot of time to know about bitcoin. therefore i have decided that i will hold your 10 bitcoin for the next higher rate and will sell it when the price touches 1000 USD.

As for me, well first, I would thank OP for giving me 10 bitcoins because hey, that's ~$7,500 free money.
Then, I will look at it. After that, I will hold it and hope for the value to go even further up. Just imagining itself is giving me a lot of pleasures. 

Dedicate a small amount for trading and save the rest.

I would put it in the Let It Ride ICO then put away the LIR for a few years, then give them to my great grandkids.
