I am trying to save my money into bitcoin on regular basis as if everything goes fine in future then my savings will grow in the best possible way.
You are doing saving money by investment but a better solution can be investing some percentage of your money in bitcoin and not all of it.
I think people have a limit the amount of risk they have. so you can not force someone to invest in bitcoin or elsewhere. although bitcoin profitable as possible for some people to take the risk would be too heavy. so the store is the best way
