What Breakthrough Solution Will Change The Future of Money Forever?

Money is just a paper, but it is one of a important living thing because if you don't have much money, you can't buy anything you need. We always using money, but there are some demerit of money. First is it's easy for treft and burned. I've written that money is paper and paper is easy to burn, so you need to take care of it. Money is very valuable, so some robbers are robbing the people's money or in bank. The second problem is it may be fluctuate the exchange routes between foreign currency and home currency. Sometimes, the dollar can be 100 Japanese yen, but sometimes it can be 75 Japanese yen. It can be equally with the country and other country, but it's an economic matter and it's hard to change by yourself.
I read the 6 objectives and I learned barter and alternative currency. Barter is same as trade. it can exchange the thing that I want and the thing that the seller wants. Barter is begun long time ago before there is money in the world and it's still doing in some region. These are the merits of barter. First is we can go to many places if the negotiation with the buyer and the seller. Second is we don't need money because barter is trade thing and thing. It's good for the poor people, but there are some demerits in barter. First is it may be unfair when the buyer and the seller's negotiation. For example, you want to buy 20kg rice, but the seller wants to have 30 chickens. It's impossible to have 30 chickens. If I'm the buyer, I don't want to buy it. So, it's hard to do the barter.
Alternative currencies is the currency, but it's different from US dollars, Indonesian rupia, Japanese yen, or British pound. It can be created by national, state, local government and many place. It can only uses inside place or the certain place. The benefit of the alternative currency is that it can't spent abroad, so the money always keeps money circulating locally. It's very good, but there is demerit. It can't use in foreign and there is limit to use it because the alternative currency can only use in one place or the certain place.
