Saving bitcoins for the future it's the best idea, if you can afford it then do it (at least try to save) and i hope that in the near future the price will be increased much more than it is now.
i do agree with you saving bitcoins for the future it's good idea but if you save bitcoin for long term does not mean the price will increase in the future because i think bitcoin price is very unpredictable and if you buy bitcoin with the current price but it will not guarantee the price will rise up in the near future
I will just add that while saving, increase their number to really feel that you are saving and take the advantage of every price rally to come. You can always make profit today by bitcoin trading. All profit must be used to buy new coins then just repeat the process of trading. Gaining profit + Increasing the no. of coins = Great value in the future.
