Its really a good idea to save bitcoin for the future and yes it is a good investment and there are lots of users of it do treat it as an investment but we should not fully rely on it because there are instances that prices might crash in the future thats why we just save or buy only the amount we can afford to lose up.
yes that is very right to say. i am also in favour of saving bitcoins for a long term. as in long term investment there are so many advantages. as i long term investment there are very little chances of losing money.
