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.
but we have to have other jobs. if we just keep bitcoin then we will not have an income every month.
keep all bitcoin held as an investment is a difficult job.
If you have a full time job then you will get income in fiat which can take care of your expenses and in that case it will be much easier to save bitcoins for future and you don't have to do anything with it and simply hold it for the future.
