Yes that's true, even if its not 1 BTC as of now in a few years it'll be worth much so it actually is not a bad idea or goal to own less than 1 BTC.
Yes if you are having a bitcoin now at least 1 i know that someday it will be big and it will huge again. So we must think that bitcoin will be an our investment for the future. It will help us so much in the near future therefore when we have an earnings we need to save some of it so that we will have a savings for a future.
