Of course i will used it for fun, i think i am going to buy ps4 and a bunch of games and also decorate my room and put new things inside of bedroom
nice plans you have, but nobody will give you 10 btc for free 
That's the saddest part of it, for sure no one is going to give 10 bitcoin for real. But well, op is just getting some reasons if ever he is going to give someone his 10 bitcoin. And there is no problem at all if we are going to think about something that we are going to do if we already have 10 bitcoin.
10 btc is huge amount and you cannot simply spend it for fun, I mean if he saves those 10 btc for future then he can have better fun by spending less bitcoins.
