for future purpose. but outside of this question, for more altcoins. 
Im saving it for fun and for future use. But most likely im saving that for future use, i believes that we may earn bitcoins now and it is better to save now and stored it , wait untik it reaches high price then sell it.Interesting sounds seems great but i will prefer to save for my future consumption i already have invested my 2000$ now it's twice above so i would definitely save for my future consumption. i hope it will be very profitable for me and i am sure i would get a huge profit from bitcoin in the future.
