For future purposes of course, why would i save it for fun. Saving bitcoins is like investing it waiting for the amount and value to rise in order for me to gain profit, maybe there are some person who re saving bitcoin for fun, maybe they just want to save it like collections , i don't know but i've known alot of user online that i've talked to that they are using bitcoins for fun, for playing games and they really enjoyed it, well for me, i'll save it as long as the price is getting bigger and bigger.
= actually i save it for future purpose because we didint know our future life some time we have a emergency in our life so that be ready for the future true saving in bitcoin. Fun is a short feeling of happiness of every people so that be ready for our future he didint know what well come.
