what the thing we can use in replacement of money ?

Money is in our trading system.Whenever we want to buy or sell something you need money,so I don't think you can find any alternative for money...

We can use what we used before we started with the whole money issue. Give service, a helping hand. If you cook for me I fix your roof. If you cut my wood I do your laundry, if you take care of my kids I cut your hair, etc. There are still people who "work" like that, get what they need. What has a "lot" of value to one person, can have no value to someone else at all.

Hi, you can use whatever is agreed upon to be considered a barterable or tradable commodity. For example, in the highlands of New Guinea rare sea shells are as good as money. On the coast of New Guinea, rare bird feathers from the highlands are used as money. On the coast of course, the rare sea shells have smaller or little value, and up in the highlands, the bird feathers are not as valuable as they are on the coast, I think they trade money, shells for feathers.

Way back before, money was not yet invented. And our forefathers used bargain or trade in order for them to avail the things that they want. :)

I think money can be replaced by something that can not be produced in surplus amounts like undilutable gold that occurs naturally in limited amounts so that its value remains same and not increase or decrease with time but then gold can be diluted and so I am just putting an idea.
